Tracker still debiting me after cancellation

On the 19th of March 2015 I called Tracker (call centre) to terminate their contract with me. I spoke to a lady by the name of Nomcebo Ndlovu and she assisted me with the process of termination. I initially also wanted a refund as i had gone to the bank in Dec to cancel Trackers debit order which stopped for about 2 months then thereafter was debited again, back dating me to 2 months. Total money debited was the R224 at the time. Nomcebo told me i could not get a refund because i need to cancel directly with them and not with the bank. Fine, on the 26th i was debited once again after being assisted with the termination process by Nomcebo on the 19th March 2015. I called in on the 26th March 2015 and spoke to Lerato Diale who told me that because i terminated mid month they would debit one more time as it was too late to cancel. April i wasnt debited,now today 19/05/15 i get an sms notification about the debit order of R224, again back dating me to April and May.<br> <br> I dont understand why its hard for me to cancel and why Tracker is still taking my money after making it clear that i dont want to do business with them anymore!! I tried to call the call centre today, NO LUCK...
