MTN Slow to Non-Fixable Service

I am very disappointed with the service received from MTN. I received two contracts, one for 100gig day and 100gig night data. Well, lets just say the contract for 150mins works fine, but for the last 5 days no matter how many times MTN rica's the SIM card, it comes up with either a RICA barred error or a call center but does not connect and come up with the 4G icon showing its connectivity to the tower for data. I am very disappointed that this has happened and in 5 days still has not been rectified. I have been in contact with the local MTN where i got the contracts, and the consultant has done what she can and MTN is doing pretty much nothing about it at this point. This changes my view of the service MTN gives that is supposedly better than all others as i have been told many times. It is quickly heading for one week that this is not working and I will be reporting MTN to the CPA and i do not believe I should be paying for something that is not working.
