MTN PATHETIC SERVICE!!!!!!!!!!!

I have to start with a bit of background. I have been a customer of MTN for more than 30 years. I have had up to 5 different contracts in my personal name and two of my previous companies were MTN exclusive customers. I have done multiple upgrades over the years. This time around I made the stupid mistake to do an upgrade online. Al went well until my handset was to be delivered. The courier company called me and asked me to spell my name as it is spelled in my ID document. I did and they informed me that it is spelled differently on the package and therefor cannot deliver the package and will return to MTN. This is more than 3 weeks ago. I have logged an online call and never received a response. I have been calling the 135 service desk on numerous occasions and every time the person informs me that they will get back to me. Needless to say nothing ever happens. I mostly spoke to Sipho. Today was the last straw. I phoned again and went through the whole process of explaining that I need my handset as my contract has been upgraded. The lady asked my ID number and informed me it was incorrect. After giving it to her for at least 5 times she keeps on telling me it is incorrect she cannot help me. I gave my phone number and again she asked for my ID and tells me it is incorrect. I told her I need this new contract cancelled as I want to move all my contracts to another service supplier as and when they come to an end. She transferred me to another department and another lady told me that the ID she is referring to is the old ID number from 30 years ago. All South Africa ID numbers changed and I now query how did I upgrade all the contracts over the years? What happened to all the copies of my ID I had to produce every time I upgraded? I was told to hold but after several minutes put the phone down. All I want is the new contract cancelled so that I can sign up with another service provider when the old contract reach the end date. I have never experienced pathetic service like this, not even with TELKOM.
