We was in contract with my partners iPhone 11 and wanted to upgrade to something newer. Was going to port the number but a very nice person at sky said we will se if we can match the deal with EE or even better it !!! He did so we agreed on the contract and as a bonus traded our old phone in. (This is where they caught us out) We sent back the phone in a PRE-PAID BOX BEWARE !!! The boxes seem to be known by unscrupulous people as the boxes with the phones in go missing hence you then have to pay the trade in value that’s been credited to your contract!! But then you’ve to try and justify your innocence of posting said item. On asking for reprints of postage at the post office and explaining what’s happened the reason why I requested it they said “your joking your not the first” !!! It seems it’s common problem with the service. I’ve endured over the last 3 weeks so much time and stress with the issue & ringing at unsociable hours it’s got to the stage I’ve ended up just paying for the iPhone 11 just to stop the calls but wished I’d ported to EE !!! Beware!!!
