Still no service after more than a year..

Dear MTN, <br> Its been a year and a half since I started telling you that my number is not working. And that I cannot make any call. However, I got billed every month. You forced me to get a new sim card but that also did not work. You said it was technical difficulties. It went on for more than a year. Email after email after email. I asked to cancel my contract but that I want to keep my number. I asked this several times. Yesterday I had to update my whatsapp application and I could not use MY number. In the same time, my mom started getting strange calls at night (3am) from my MTN number. <br> <br> Why has my issue not been resolved after all this time? I do still have my number? And when will this be sorted out. I have not been able to get into my banking accounts as the number is used to access the accounts. How much more of this should I take?<br> <br> Please get back to me urgently. <br> Kind regards, <br> Jaco <br>
