FALSE PROMISE

I joined Virgin Active Sunward Park and was promised Adidas voucher of R900. i instructed them to debit on my account on the 25th, but in October they didn't debit so when i realised that i went and payed my account to the club immediatily. then end of November i went to the club and spoke to the reception lady and she said she did'nt know anything about the vouchers i must call the head office when i call them they said the the vouchers will be issued from the first week of December. i waited till yesterday i call again the head office but now I'm told that i didn't qualify because my account is in arrears but i asked them how because i paid my account before month end. the call centre agent said that my account is in arrears because they didn't receive that my payment in October. but how because i did pay before the end of October. the Call Centre Agent is sending me back to Sunward Ward Park to speak to the manage. WHY DID THEY MAKE A PROMISE THAT THEY KNEW THEY COULD NOT FULFIL. FALSE PROMISE disappointed.
