I ordered a replacement iPhone5C at a reasonable price from Quick Mobile Fix, which was promised in 3-5 working days.

After over 2 weeks of ringing, being promised a priority delivery the next day, and no phone ever being dispatched, I'd had enough and cancelled my order (I suspect QMF sold me a phone that they didn't actually have). I was then promised a refund in 3-5 working days.

It's now 10 days later and, surprise surprise, I am yet to be refunded. I'll be taking legal action unless I'm refunded within 48 hours.
