My number was ported without consent to MTN

I dont know if this would even help, but I would like to inform you of the complete and utter disgraceful service that I received from your company. My number ***) were *******ly ported from Telkom to MTN last week, now keep in mind that this is my work number and my banking details also connected to this number and that I spend R4000 on advertising my estate agent company the previous week also with this number. This has still not been sorted out, this has cost me a lot of airtime and time, and still no one at was able to help me. THIS IS A HUGE PRIVACY BREACH, and no one can tell me how this happened. I went to your store in Bloemfontein and there I waited for almost an hour 2 days ago and this morning as well, because of staff issues as there was 1 sales person and the others were on training. This is a disgrace how you treat your customers and our privacy!! I was unable to work in this week and lost money and business, but you dont seem to care about it. Pointing fingers to MTN wont help, as Telkom had to give authorisation to release my number to MTN. I am ashamed to call you a South African business and wont recommend you to anyone!!!
