VM charged me wrong bill (5 times from previous one) after moving home and new contract without consent
I joined VM in Feb 2023 (18 months Broadband with VM) with a promotional price £14.99, which expires in Aug 2024 theoretically.
I moved home in March and notified VM around 21 March for 'MOVE HOME' via live chat with nothing change on my plan, just stay the same for the remaining of my contract. They checked and said there will be a faceplate set up in my new place and account will 'GO LIVE' after installation completed.
VM and their 3rd engineers failed to set up for me after 4 visits on 4 days, the last fail visit was 24 APR. Eventually I only have broadband connection on 1 May, but they still put 'GO LIVE' date as 24 APR which is ridiculous, as their engineers left and said no way to complete set up on 24 APR!!
Despite the wrong 'GO LIVE' date, I found my bills were charged ridiculously high, £14.99 changed to £71.00 per month, and the contract which should ends in Aug 2024 seems changed to Aug 2025 that they put a new contact to me. I witnessed that before bills generated in MY VM portal, I called multiple times and the CS kept saying 'No need to worry, things will be adjusted in your first bill after moving'.
However, things still keep going wrong and I feel like I was scammed VM as they did not do what they promised.
Can anyone can help or advise me on this please, as I have had enough with calls to VM, just simply useless...
What I want is just to live with the original contract I signed, I didn't agree any change on a new contract or service in any conversation.
