Subscription not cancelled as requested

Good day<br> <br> On 4/02/2015 i phoned multichoice asking them to cancel my subscription. the lady on the call centre said that i pay in advance and that my subcription will be cancelled 26/02/2015. also my debit order will be cancelled and that i would not owe anything as my subscription is paid in advance ahead. On Friday 27/02/2015 i phoned to follow up if this was done, yet it was still active and i got bill to pay a monthly installment. I have send to their enquiries a mail but they said back on the mail it was only cancelled 27/02 and that i owe them still money. I asked them to pull the recorded lines. On friday 27/02 the call centre guy luaghed over the phone when i did my complaint when i asked for the manager not knowing i could hear what he said to his partners with him. he also said that they would reverse the account against my name yet it has not been done. I need urgent action and assistance as this will reflect badly on my good name at the credit department due to *********** staff not doing what they said they would. i cannot be held liable for this account and want a letter stating i do not owe them anything as it was not a mistake on my part at all.
