No service and feedback

I have a limit set on all my lines provided by Telkom Mobile. In February, my account went over my 700 limit on line *** and I received an account for more than 4000 - almost 4 times higher than the limit. I have queried the reason why the limit has not warned me and blocked the account as the reason for the high account was roaming charges which was higher than anticipated. I have sent more than 10 mails and after 2 month have not received any feedback yet. I find this unacceptable. I have now decided to close my accounts when they are due for expiry. I will send my notice for every line on the first day of the month preceding the expiring date. I do not want to continue this business relationship any longer. Please take this as cancellation of Line *** due 22/05/2016.
