Very bad service

Im raging with MTN, after falling behind in payments, i contact the legal department to settle the account. They give me 2 options to catch up with payment or settle and get letters for either confirming the payments. 3 weeks later i am still waiting for the letter then i end up clearing the account to get rid of them in totality. They dont respond to emails of request, been on the phone holding on for legal for over 30mins listening to music that hurts the ears. MTN has made their money, i dont know why they still in business because their customer care is not there and they dont actually care. MTN needs to shut down and stop fooling us as if they care, they just care about getting your money thats all.
