MTN is a ****!!!!!!!

I took out a contract with MTN- this was the uncapped WiFi router, I received the router on the 2nd of November but unfortunately it gave me hassles, I called the customer care line and they were helpful but we quickly came to the realization that the store used an incorrect address. I called the store and they said that it had nothing to do with the address and that I should bring the router in to have it checked, I did just that and still they couldn't fix it, they then replaced the router and told me to activate it online by calling 135, I also believed them and I called 135, I was then informed that there is a barring on my number and the store should fix it, during this period when I called or went to the store they either had loadshedding or they asked me to wait for the lady who assisted me to come back from leave! Finally on the 6th of November I went back into store cause I was fuming as MTN is taking me for a joke and I spend thousands on of Rands on data. On the 6th of November, my contract was canceled and a new one was loaded (great so problem solved or so I thought) on the 17th of November I receive my Bill which was R1960, I nearly had a heart attack but when I checked the invoice I was charged with 2 routers, how?? When I only have one operational.. then I start the entire process again calling 135 and asking what's happening, they inform me that both routers are active and I said to them thats not possible as I have received an email from MTN confirming that the one is canceled, the lady tells me I should take it up with the store.. I call the store and no one is able to assist cause the girl that I dealt with is not in... I go back and forth calling MTN costumer care and the store, a gentleman helps me at MTN costumer care and tells me when they deducted money from my account I should reverse it and dispute the amount. On the 25th the set amount goes off on my account I then call my banker and ask him to reverse the amount which he does... minutes later I receive message from MTN stating that they will cancel my subscription unless I pay the amount, I then go into the store and tell them this, another lady assisted me and then noticed that an error was done on my account, there was a request logged but it wasn't dealt with, she gave me a number to call to escalate the process, I then Indicate that the number that they requested to cancel is the one I currently use, which was started on the 6th of November, she then says she will log another request etc.. a day later, MTN canceled all my services due to payment, I call customer care and tell the lady what is going on and say that I Won't pay for 2 routers when I only have one which is operational and she then says I need to make a payment plan so she can just activate my line and hopefully everything will be sorted by the time I need to pay which was set for the 15th..

Did I not call and message MTN on a daily and each time they tell me a request has been sent etc!!! I am more the annoyed now cause I paid R1200 the other day cause they again stopped my services and told me this will harm my credit score( and I don't take my credit score lightly) needless to say I just received an email again stating that I owe R760 and if not paid services will be ended.

MTN has not sorted out my issue and it has been nearly 2 months now and I refuse to pay for 2 routers when I only have one active and yet they quick to send emails etc but can't solve a problem!! I am disappointed and disgusted by MTN and now regardless I have to pay the R760 or else my credit score will be affected!!! This is annoying and unfortunately as I am paying for a service I did not receive!!
