Lets do as we wish

I have spoken to three call centre agents, Pauline, Patricia and Koketso.<br> <br> My complaint is this:<br> <br> On my contract it states, on my signed addendum:<br> <br> Paragraph 6:<br> <br> The Monthly membership will escalate at CPI or 10% per annum, whichever is higher, and will be escalated on each annual anniversary from when the debit order came into effect and will continue for as long as the membership remains in force.<br> <br> Now, the debit order came into force on the 1st of February 2015. In July 2015, a higher fee was taken off my account via debit order as well as the double levy at the increased rate. The annual increase should only take place in 2016. Please refund (Jul x 2 & Aug) me the difference and return the debit order to the agreed amount as per our contract. <br> <br> My reference with you is PF***
