Swapped my phone

[Joannielew]

Hello I swapped my phone last month and sent my old one back i was not told that I still will have to pay for my old phone. I had 186 pound left to pay so they said if I send my old one back that is all I have to pay so I did when I had my next bill I still had to pay 31 pound gor my old phone

When did you send your phone back?  It normally takes 2-3 weeks to process.

However, it's the busiest time of the year (iPhone launch) and can take longer...
