Bad service

I am really tired and so helpless with MTN. From the 16 April 2020 to date I am unable to receive calls and they don't know what is the problem and they took me from one consultant to another. I really wouldn't want anyone to use MTN for who they are. Prepaid tells me my number is under contract and contract department tells me my number is on prepaid. Back to prepaid they say my number is migrated to ilula which no assistant is as well able to assist as they also tell me my number is prepaid and probably my phone settings are not correct. THIS CAN NEVER BE A BOZA NETWORK.
