Issue following contract renewal - incorrect monthly cost showing in my account

Hi all

I'm looking for some help to hopefully address/alleviate concerns I have following my contract renewal.

In short; my previous contract was due to end in August (monthly cost £89.50). I chatted with an agent via the live chat last week and was offered a 24 month renewal for the same services at a price of £81.50. Happy with that, I agreed, had all the documentation through various emails which is all in order and as per the package offered, new hub arrived in the post as promised and all set up, everything working. Great, all good so far from that perspective.

However logging on to my account via My Virgin Media, I am worried. The information on there on monthly package on there has updated - however to something that bears no resemblance to the actual contract I have agreed/signed up to and had send to me in writing (exorbitant monthly cost of 144; services different to what I've got eg 500mb instead of 1gig, no sports ultra hd). And what is more I have had my next bill generated which is again different to the amount I had confirmed to me by email setting out what my first bill on my new contract would be (even taking into account the double billing for the first contract payment).

All of which is making me very uneasy as to what has actually been put on to the system. I have seen from a search on here that people have had similar issues in the past but it is hard to know sometimes what the resolution ended up being. I would therefore be really grateful if someone from VM could please contact me via PM to help - where I think essentially I'm after some reassurance/clarity on a) has my new contract been put through correctly as per the documentation sent to me, b) what exactly will my next bill be/will it accurately reflect the transition to my new contract, and c) can I ignore the info currently showing by my account in MVM/will it eventually update...?

Many thanks
