False Information

At the beginning of the month, I received a phone call from Virgin Active regarding my contract, we had sorted everything out over the phone, now i get a sms and a phone call from a debt collecting agency stating that i have handed over to them for payments even after Virgin Active and myself made arrangements concerning the payments, i have the recordings for everything as proof. Now I get told that the fee is higher than i was told in the first place, this is unacceptable.
