DISGUSTING SERVICE FROM CONSULTANT

I am absolutely FUMING!! This is the 3rd or 4th time I am reporting this to Hello Peter. I cancelled a contract with Cell C in September 2012, the date which their call centre consultant gave me. In October I was double debited and visited the Bayside branch. They checked on their system and everything was clear, so the manager at the time advised me to reverse the payment, as it wasn't supposed to be deducted, which I did. In January 2013 I started getting calls from MBD attorneys to recover the unpaid month. After 2 1/2 years of fighting back and forth, phoning, requesting recordings, sending emails, I phoned the legal department to find out what was happening. I have NEVER in my life come across a consultant as arrogant and rude as the one I spoke with!! I was trying to explain what happened and she kept interrupting me, upon which I asked to please let me finish. All she kept saying was \you signed the contract
