No feedback - contract cancellation

Hi,<br> <br> I need to cancel my contract. The bank account will close at the end of the month so it is very important that I pay the required amount ASAP.<br> <br> I have requested the cancellation figure on the 17th August. At first it was going to take 48 hours. Then it was going to take 48 working hours. Now I'm told it takes 30 days.<br> <br> I can't get hold of anyone that will help as I'm told the department working with this does not take calls so I do not know if my request is being ignored.
