Over a month and no resolution to ********** transactions on my account

After my phone was ******, I went to a MTN store the following day to replace it. The SIM swap that was done didn't work and the people that stole my phone were able to rack up a bill of over R8,000. The store told me to call the call center to resolve but when I did so, they told me that only the store could resolve the issue. I had to drive a long way to get back to the store who told me that only the call center could resolve this. The issue was escalated to the store manager who promised to resolve but nearly a month later, nothing has been done. On calling him the whole game of pass the buck has started again. I'm passed angry and have moved on to amazement at the level incompetence and lack of ownership.
