Virgin Active N1 not refunding my money

I have been waiting since end November for N1 Virgin Active to cancel my membership with them. As they kept having problems activating my vitality. Only recently they cancelled my membership. There have been numerous emails and phone calls between us to refund me my money back. The club general manager promised to sort this issue out and get my refund done. But still nothing. He keeps on telling me the money will be paid out, but nothing is coming from that. I have been very patient with them. Last week the 3rd of Feb 2015 I was emailed by another club general manager, to let me know that my refund was processed on the 2nd of Feb 2015 and the money will reflect in my account within 5-7 days. Where is the club general manager of N1 virgin active? It is his duty to get this done. Now today is the 11th of Feb 2015 and no payment received yet. I have send them (both the club general managers) an email enquiring about my refund and no one has rep**** to me or phoned me. Clearly they don't care and is expecting me to chase after them. This is really tiring....
