MTN SUPERFLEX IS A ****

I am an MTN subscriber for more than 20 Years On the 28th July 2025 I took out a new superflex pre paid unlimited calls sim card which I had paid upfront. I received the sim a few days later & the the sim was rica'd with my ID & utility bill with the MTN courier guy that delivered the package. Days later the sim was still not rica'd, we then had to go to an MTN store to ric'a the sim again! We then realized we couldn't make any any phone calls, as a voice message says insufficient funds to make a call. I called an MTN 135 number on Monday 04/08/2025 and the person said the matter would be escalated & I will be connected between 2 to 24 hours, this never happened. I then called everyday waiting on the line for around an hour for assistance & each day I had to speak to a new consultant telling the same story everyday. I was repeatedly told by the consultants someone will call me back & they will escalate it & get a supervisor to call me back which they never did. During this time one of the consultants mentioned that an incorrect package was loaded onto my superflex sim card therefore the sim will not be able work & it will be corrected but till now no one seems to know how to correct this problem. Its now another week later with no help from MTN consultants & supervisors, no calls, no emails, no communication. I am still unable to use my sim card which I have already paid for. MTN IS A ****!
