Trying to cancel my contract since February

At the end of February 2015 I cancelled my cellphone contract from Telkom Mobile, sending a form to [Email Removed] I received confirmation on the 05th of March by a return email and that someone would call me. On the 12th of March, Bianca from Telkom called me to say, that my contract would expire the end of March. On the 01st of April my contract was still active. The 13th of April I called the call centre and spoke to Bruce Carlinsky and he told me that my contract only expired the end of April. On the 01st of May my contract is still active. I called again the call centre on the 02nd of May and spoke to Tako Khumalo, she told me that all these people never cancelled my contract and that on Monday the 04th of May she would call me back with a answer why this contract was not changed.<br> <br> This is pathetic service, back and forth and no substantial answer. I refuse to go to a store as this was possible through sending a email to retentions.<br> <br> I will never sign any contract with them again. Bad service and bad correspondence.<br> <br>
