I recently bought a phone from carphone warehouse and a 1 month £12 virgin media contract with it as the phone was £100 cheaper that way.
I didn't want the contract so phoned up and attempted to cancel it within the grace period.
I was unable to get into my account with the first two people on the phone because I didn't have the account number (Never sent it!) or the password (Never set one!). The attitude of the operators was disgusting as they told me I set up my password and should know it - I have never had a virgin mobile account before, nor had I received any information from virgin mobile other than the flimsy sim pack which contained nothing useful.
The third person I phoned was very helpful and forwarded me to cancellations who then attemped to charge me for the service. I reminded them and they stopped the charge - "Oh I didnt check, sorry sir". I was told that was it and I wouldn't deal with virgin mobile any more. Knowing that something bad would definitely happen I cancelled my direct debit. I also binned the sim.
Then about two weeks ago I received an email telling me I owed £12. I phoned up and the man on the phone told me that I had used the sim. Yes I had, I'd used it to get a text from virgin (hoping there'd be some account information in the text) and to call virgin. He told me that meant I didn't fall in the grace period. I then explained how absolutely ridiculous that was and he "waived the fee" - strange because I didn't exactly owe you anything did I. His tone was also quite belittling.
Now I've been sent a bill, two weeks later, for £5.58.
