POOR SERVICE

I am EXTREMELY unhappy the way I have been treated by MTN as a whole, being a client for 20 years.<br> Noticed a very high Data charge of R2792.24 on my Internet ****le on 07/09/2015. My normal charge is R129,00 per month & I still have 600mb CREDIT. <br> Immediately logged a query via phone & email.<br> Kept on following it up with customer service , BUT to no avail after 3 weeks. <br> Yet they had the audacity to DEBIT my Bank Account with this ERROR amount plus the normal charges, while they are still investigating!!<br> Manager informed me that is how it works and I must just ACCEPT it !! :-(<br> If it is an error on their side, they will credit me in 21 days !!<br> I am going to try & reverse this Debit myself via my Bank.<br> THIS IS A VERY UNHAPPY MTN CUSTOMER.<br> Thanks<br> C van Nuwenhuys
