Having upgraded to a "Good As New" handset, which turned out to be unusable as the previous owner had forgotten to untether it from their email account, I spent a week-and-a-bit making phone calls and visiting my local EE shop until the matter was resolved. The call centre and shop staff that I dealt with were as helpful as they could ever be, lovely and professional people. In the end, I got a brand new mobile as they were out of stock of the "Good As New" range (which, to be fair was as good as new, apart from the aforementioned comlaint). My rating for EE's Customer Service has jumped from a 1 to 4 stars. It would be a 5+, if only I hadn't been the one who had to guide them through the whole "how-to-sort-this-out" process in the first place. The coverage, especially with the WiFi Calling feature is the best I've ever experienced. Overall, I love EE. Just be prepared to moan if anything ever goes wrong.
