USELESS!!!

I have 4 contracts with MTN and decided to close 2 that I didnt need. I contacted the retentions department and was given the amounts that needed to be paid. I kept asking if that was the full amount to be paid and was advised that it was. I paid the full amount, sent proof of payment and the contracts were converted to prepaid. They then decided not to debit my account for the remaining 2 contracts. I tried contacting them but realised i have a better chance of getting pregnant than getting through to their 808 helpline. I sent an e-mail and 8 days later received a response that someone will call me within 8 hours. 2 days later and still no response. Now I received an sms saying that my account is overdue. IT WAS YOUR FAULT @##%^$#@ wake up. Appoint people that know *** they are doing. I have been holding on for 25 minutes on 808 to get through. Guess what...I will be closing the remaining 2 contracts with you as well. @#$%^$@ useless
