Virgin Active account department is the worst ever!

I am absolutely shocked at how they conduct business. There account department sucks to say the least. After 2 years of my contract being cancelled I have been handed over to attorneys. No call, no SMS, no email from Virgin Active to even let me know that there is still money outstanding. 18 months later and then you get handed over without any notification or chance to sort it out. I am requesting a reconciliation on my account with them and they refuse to give it to me. The attorneys refuse to give it too. I must just pay what they say without me being able to check if all payments has been allocated. How is this even possible?
