Failure to provide my PUK number as promised

I signed up with Mobile Plus in March this year, for the airtime and sms contract per month. I then faced a challenge whereby I blocked my sim card accidentally, this incident happened in the first week of April. I requested my PUK number from Mobile Plus immediately after I was advised by MTN, I have not received any assistance from them to date. I have to call them countless times and each and every time I'm told my PUK has not been sent by MTN. <br> <br> When I reported the matter they said it will take 72 hours max to solve it and here I am exactly 2 months later and nothing still hasn't been done. I have sent countless emails to their support and to my SURPRISE TODAY THEY RESPOND AND TELL ME THE PERSON RESPONSIBLE IS ON LEAVE!!! Are you telling me there's only one person in the entire company that deals with queries??? I would never recommend Mobile Plus to anyone because I have never received good service from them. I have expressed how urgent I need my PUK and how I really need access to my phone but clearly they are not bothered. I AM A VERY UNHAPPY CUSTOMER!!!
