Sim Card still not working after 10 days

On 11 November 2017 my car was broken into while I was running a half marathon in Stellenbosch and everything was ******. Obviously I had to get my number back so I went to Stellenbosch MTN - who was rude, would not help me at all and shouted at me. This was not appreciated as the day was already a mess. I decided to go to Cape Gate MTN rather after the terrible experience in Stellenbosch. Cape Gate MTN was great, the staff helped me immediately, they told me my options ( as I am on contract) and we did a sim swop in about 3 minutes - Fantastic! Great service! Today 20 November 2017 my sim card is still not active, I cant do payments ( my OTP pin goes to that nr), I cant get into my Living Complex ( cell to gate system) and my clients cant get hold of me because of this. Cape Gate MTN says on their side its through and active, but on some or other main system its inactive. I have now phoned everyday since 13 November and no one is able to help me with this problem. Come the end of the month you want me to pay for a contract that inactive and can't be used???? How can I pay for a service that is not given to me?
