Bad Call Centre, Bad attitude

I have been trying to cancel my tracker since Monday 1 June 2015 phoned on 4 different occasions (speaking to 4 different people). When finally being transferred to an supervisor(the second supervisor seeing that the 1st one didn't call back) this supervisor Shaun Steyn gets irritated and annoyed at me for insisting that it should be cancelled today(a week after i have been promised it would be cancelled),stating he is not the supervisor of that department so he cannot guarantee cancellation today.(not helpful at all,not even offering to transfer me to a supervisor of this specific department) I then insist on a direct line to call back on if it is not cancelled by tomorrow morning, he then gives me a number claiming it is his direct line (which i have just phoned and once again it is a call centre number)when i ask him to repeat this number because he read it so quickly, he patronizes me by reading one single digit then pausing and waiting for me to say yes before reading a next digit...how rude!!! What absolute horrible disgusting customer service!! In my live i will never do business with you again!!!
