Pathetic service

I cancelled my contract with MTN as I had 4 phones with them and one I paid it off and asked cancelled it. Called the MTN call center and the lady who was assisting me dropped the line as she was giving me incorrect information and I was still billed for the cellphone that I cancelled and paid off. MTN they are good when it comes to calling clients when they due for an upgrade otherwise their service is pathetic and poor. I wouldn't recommend MTN to anyone.
