I have an identical issue with Unicom as CAG member M1JWR (title 90days) March/April 2012. I.e. Unicom imposed their own contract after company merger. The information I am getting from Ofcom is not quite so clear cut, because 5 months has passed since being advised (identical letter to that quoted by M1JWR) it could be interpreted as acceptance. I can see from the thread that the 2007 Elite Calls contract is valid, and I have persistently advised Unicom to that effect. I have not agreed to accept the changes verbally or in writing. I cannot see whether M1JWR had a successful result & if so how it was achieved. I should be very grateful for an update if anyone is familiar with the case. My case details are as follows: The notice period extention brought forward the notification deadline to 7th June. It should actually have been 7th August. Quite by accident I found out about this on 5th July & immediately emailed 2 months notice to end the contract on expiry in Sept, a week or so later when it became apparent that Unicom were playing dirty I backed it up with a recorded delivery confirmation (to ensure I complied with the Elite Calls T&Cs). Unicom rolled over the contract until Sept 2013 and are demanding their usual £395 early termination fee. There is a further reason why Elite ‘wholesale business plan plus’ customers like me should be able to leave the contract:-Elite guaranteed no price increases for the duration of the contract. Unicom has increased the tariff; thereby customers should have been advised of the option to terminate because there had been a change of ‘material detriment’ to the customer. Unicom withheld the opt out information. However if Ofcom are right I could lose this 2nd argument as well. Its the Ofcom opinion that is is bothering me.
