STAY CLEAR OF VIRGIN MOBILE!!!

I cancelled my Virgin Mobile contract at the end of October last year. I gave 30 days notice (actually more, as I phoned to cancel on 22 October already) for my contract to be ended at the end of November. When I phoned to cancel, I clearly stated that my contract was expiring and I did not want to renew it. I was given a reference number VRMM***7. I checked and double checked with the call centre that my contract was ending at the end of November, as I wanted to take up a new contract with a new service provider. I was assured that everything was in order. I went onto a new cellphone contract at the beginning of November. However, at the end of November I was billed again by Virgin Mobile for a full month. I enquired and was told the reason is that my contract was only cancelled on the 5th of November. My contract wasn't cancelled on the 5th!!!!! It was cancelled on the 22nd!! I only phoned again on the 5th to ensure that everything was in order, as Virgin has disappoint me to many times during my contract time. If I wasn't billed double, my phone was cut as they loaded the wrong bank account number, etc, etc. I can go on. I refuse to pay for a service I didn't use.
