So it's been around a week since I put in cancellation currently paying £25.80 for 250mb which rises to £42.8 when contract expires in October
Via live chat I was offered £20 when putting in cancellation I declined it , I did go back via live chat few days later and now best they can offer is £23
I haven't received any calls but have received email about tempting me to stay for 10% off which makes it slightly over £23 but reading Reddit someone posted they received 3 emails all few days apart each time with better offer
I did receive a text message to call a number to discuss I think that's probably to retentions
I still have a few weeks before service stops so will wait to the very end see what they might offer , I'm not worried about service going off as I've got 5g SIM from ID mobile unlimited data for £15 rolling monthly using on spare 5g phone tethered via usb into Asus router, getting on average around 150mb not had any issues with few devices streaming and 4K
