“I recently encountered a persistent "500 Internal Server Error" on the Mobiles.co.uk website while trying to purchase an iD Mobile 50GB deal. After a phone call to sales didn't resolve the technical glitch, I used their online escalation form to report the bug.
I was impressed that the issue was investigated and fixed by the following morning. I was able to complete my purchase before 10 AM. While the website error was frustrating initially, the speed of their recovery and the fact that this is easily the most unbeatable deal on the market (especially with the cashback) earned them this 4-star rating.
If you encounter a website error, I highly recommend using their formal escalation path—it actually gets results.”
