MTN does it again

I laid a complaint about a month ago, regarding poor service from MTN (refer to that complaint for more details). Consultant from MTN contacted me, (Dimakatso Tshabalala), said if i experience any further issues to e-mail her and she will respond, i mailed her on 05/10/2015 and had no response, I called her on the 15th of October and asked ifshe got my mail, she said she was assisting the last time and was not responsible for any further assistance, what i cant understand, is why did she not forward the mail to another colleague to assist, or respond to my e-mail and let me know who to liaise with. I just went to the MTN store now in Sandton City, where i renewed my contract initially, the consultant there now saw the issue and they are busy resolving it currently. According to the consultant, they did not load my sms and data bundle correctly. I did tell them to also look at my bill for last 2 months and refund me for incorrect charges.<br> This is pathetic service, everytime I called why did the person assisting not see the issue, it eventually had me going back to the store to resolve. Sad to know such a big service provider got it wrong like this.
