Got eventually there. On trying 150 online a recorded message just says not enough credit to make the call. Need to top up but does not advise how. Waste of digital effort.

On-line top-up worked reasonably well, but my 1st attempt failed miserably and I needed to get assistance from EE (top-up) help line, but in the end, they sorted it out for me.

About On Top Up
Written by the company
On Top Up provides an easy way to purchase topup vouchers and credit for Pay As You Go mobile phones. We cover all the major phone networks, allowing users to add multiple phones on different networks to their account, and topup whenever they need.
Please note, that any accounts that opt-in to Auto Topup will have their subscription renewed automatically each month, and for security purposes you will need to log into your account in order to apply the credit to your mobile phone.
Our optional Auto Topup service allows users to automatically buy a topup every month, to help ensure they never run out of credit on their phone(s). The Auto Topup service can be started and paused or cancelled at any time simply by clicking a button in the user account area.
Our Customer Service team are on hand 24 hours a day to help out with any queries you may have. Click the Contact Us button below to send them a message or give them a quick call. If you have any queries regarding your account, please call or email us rather than leave a message on Trustpilot, as we will be able to help you much faster.

ontopup scam - non redeemable voucher
Checking my credit card statement I discovered ontopup had set up automatic 30 day payments without my knowledge. I contacted the company by phone and instructed them to cancel all payments. I received an email saying the automatic payments had been deactivated and that I had a voucher to redeem After several more emails with automated AI responses, I could still not redeem the voucher. I did reach out to ontopup support who repeatedly claimed to have emailed links which I never received. I will not be using ontopup again and would advise others not to use them.

Unaware that subscription was taken
Ontopup was useful when we needed it (whilst on holiday) but we thought we had bought a one off top up. In fact they had signed us up for a monthly subscription which we only noticed after paying for unnecessary credit for 6 months. Check any emails from Ontopup if you have used it. I ignored earlier emails assuming they were something to do with my partner's phone and his travelling.

My partner askwd me to to up his pay as you go phone just once, which I processed on my computer a few weeks ago. Today I get an email that Ontopup has debited my gmail account charging a fee of over £40. At no time was there an agreement to a regular top up on my gmail. Partner is now terminally ill in hospital and I am reduced to even more grief over this. My only remedy if it is not cancelled without delay will be to put it out into the mainstream media to get a result.

reported to my bank and action fraud
reported to my bank and action fraud. I received an email that a mobile using my credit card has been topped up. I never made the purchase and do not require top up. All my purchases require consent. This company got around this security and took money from my account without authorisation. I have attempted to contact this company and they fail to reply. Dishonest and criminals who participate in such activity.
response to this disgraceful genric reply
you cannot find an account? you will not as i do not have one. you used my credit card and stole from it. you are criminals and reported to trading standards. you have been issued with a formal request to return the funds you stole or face further negative reviews. judging by the other reviews, you are familiar with stealing money. you have been given 48 hours to return the money you stole.
