Incompetance is the order of the day

Since 22 April 2017 I have been truing to cancell a contract. Going to mtn stores is pointless because just mentioning the word cancellation and you are being treated as if you are mentally ill. Phoning 808 and trying to convince the operators to help with the cancellation is a task not to be undertaken. Emails to mtn customer service is a headache. I am still being billed for services that should have been cancelled and my one number even suspended for apparent non payment, but the incompetant people working at mtn does not know how to cancel contracts.
