Bad Service

Please please help me.MTN is deduction money from my account. And keep on sending email and do not solve my problem.This is really getting ridiculous.Please find attached all my correspondence so far to MTN. I Cancel the contract by telephone and do not have a cancelation number. MTN collects the instruments from me. MTN sends me all sorts of emails, someone else every time.I repeatedly phone with no answer. I Send emails that took ages to be answered. I went numerous times to MTN direct in George to find them either closed or off line. I went to the local MTN agencies in Mosselbay and they locked a query. Just all the emails .With absolutely no positive results? I am Really Really getting fed up now. And need to urgently talk to someone who is able to assist me. Regards Christa Croukamp
