Problems with new sim transferring from rolling contract to pay monthly

[Dissatisfied1]

I recently took out a VM/O2 package meaning my contract with O2 changed from a rolling monthly one to pay monthly. O2 sent me a new sim which took 3 weeks to arrive and as I was paying for a whole month I received a credit, which was very welcome. I activated the sim and had O2 change my number to the new sim. Problem was my rolling contract had a week to run, which meant I would lose a week of benefits, which I didn’t mind. However now that week is up I find that I’m still on the rolling contract and I can’t make calls unless I pay for them! What should have been a simple switch over has turned into a nightmare. Puts me off recommending O2 to anyone.

We’re just customers like you but it sounds like you’ll need someone to access your account which can’t be done from here. If you message O2 on Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG) , they should be able to help you with this
Thanks
