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.

Inadvertently used this site
Inadvertently used this site. I bought £10 top up and was charged £11.89. This charge was not clear on the website. I rang to get a refund but was told they could not do this. I then got an email to say that the account I had set up included automatic top ups and those had been cancelled. I did not set up an account or opt into automatic top ups. Had I not rung in, I would have incurred automatic top ups. This company is not a scam but has some dodgy and unclear practises. Avoid it at all costs.

Don't use this Company.
This has to be the very worst Company I have ever encountered. When I tried to top up my 'phone online this was the first one that came up and it gave my 'phone company so I clicked on it, thinking it was my Company. BIG BIG Mistake. They are dreadful. (Customer service shower need a bit of training).I contacted them and said I hadn't used the receipt and asked for a refund. They refunded the money (so far so good) but then because of the way it looks online my Husband did the same thing but this time they told me that it was non refundable. (?) not only this total inconsistency but they also change a "processing fee" which meant the £15 top up was now almost £18. Steer clear of them they are dreadful. I have read their reply, whatever happened to the 14 days "cooling off" period when buying goods and services online. As I said at the start of this review The Very Worst Company, ever.
