Erin and Dawn were polite
Erin and Dawn were polite, straight and helpful. Couldn’t wish for anything better. I think the company should really look after them and give them a big pay raise. They have been very helpful to a pensioner who forgot his glasses

Amazing! Changing to a completely new device can feel incredibly daunting, so it is wonderful to hear that Erin made the whole transition so smooth and stress-free for your mum. Taking that extra time to clear out the clutter and personalize the setup is exactly the kind of care we aim to deliver. 😇 -Prabhjeet
excellent service….
Received excellent service from Dawn today, although I’d transferred to Three from another network and via a third party, due to an issue with my SIM card not registering in my iPhone I went in for help! Dawn had no problem reassuring me and sorting the problem within 10 minutes - I am extremely grateful and would highly recommend this store! Thanks again!
