Contract Information Sheet Price Different from Final Contract Price

Hello,

Back in May we ordered broadband with Virgin Media at a monthly cost of 28.99 (M350 Broadband), to start in June - this is stated in our "Virgin Media Contract Information Sheet", which was attached in an e-mail titled "Virgin Media Order Documents". Given the price was as expected, when a new e-mail arrived 2 hours later that same day with the final contract (titled "Your Virgin Media Contract"), we didn't pay it as much mind, but it turns out it states that our contract is that of 66 a month. We have noticed this now that the normal monthly billings have begun. 

How is this possible? The only reason we went ahead with an 18 month contract with Virgin was that we considered 28.99 a fair price, and that is what we ordered and agreed to. We never agreed to 66 a month. 

This same issue seems to have been reported in past threads: Contract price different from the pre-contract documents I agreed to | Virgin Media Community - 5639131

We are now trying to get hold of customer service to no avail and are turning to this platform for assistance, please help us solve this.

Thank you.
