With regards to upgrades I am afraid they cannot be dealt with in the forum. The prices on the website are for new customers only you will have to re-negotiate your contract with VM.
Due to the current situation there is a text message only service is available via: 07533051809 Just send a text with the issue you are facing and someone will get back to you as soon as they can. Please bear in mind at this time this service does also have a high load and may take quite some time getting back to you. You can also call in on 150 or 0345 454 1111 best times to call are first thing in the morning, use the option "Thinking of leaving", but again wait times my be long.
I have just noticed that I can now get a top internet speed package of 500mb for £46 a month. (Without the oomp deal)
As Mike has said - the standard price for "500 BB only" is £62/mo (350 is £56) that's what you will be expected to pay unless you can negotiate a better deal.
