Virgin doubled my bill via a phoned sports package upgrade I was sold. I have complained and had it removed but the phone to complain cost £14.76 this is outrageous. I fear phoning you back to complain again due to this rip off charges.
Did you find the number via a website? There are many dodgy sites which connect you to Virgin or whoever you're calling but via an expensive premium rate number. There's no way the normal 0345 number would cost £14.
I'm glad to hear the error with your bill has been corrected, sorry for any hassle caused chasing this up.
With regards to the charges when calling - what number did you call us on? We have a free number for our customers (150 from a Virgin phone) and our other number 0345 454 1111 is standard local rate (equivalent to a landline call) and would usually come from your minutes allowance on a UK phone package.
