POOR CUSTOMER SERVICE and Adjustment Fee Scandal

Received email with "Adjustment Fees" last night from Virgin Active in the middle of my contract period! It is not an annual increase. They are adding R110 per month which is not in the contract I signed. In the annual contract there is a annual increase but not an adjustment fee... I am furious and will not accept this increase, I also held for over 10 minutes, was cut off and then had to phone again and wait another 10 minutes again. After finally speaking to them the put my through to the "Retention" Department as the lady could not help me....Once with Retention department they cut me off AGAIN!!!!
