MTN USELESS AND ******

i have been trying to cancel my contract forever with MTN they are useless and no customer service. they ignore my request and then they want to block me when i tell them i will not pay my account until they acknowlage that i want to cancel this contract, after 6 weeks of complaining, phoning, sending mgses on facebook i finally got through to them today just so that the guy can tell me i must phone back tomorrow. this is pathetic to say the least and then to hear i cant keep my 1gig data and almost R400 that is on my phone, 1st i paid for that R400 airtime and i cant change that over in data so i have to buy data extra and now they want to tell me i cant keep that. that is beyond ridicules. i want to keep my nr go over to pre paid and i want my data and airtime that i paid for. MTN IS PATHETIC. Then aswell the guy that i spoke to today decided he cant deal with my complain so he put the phone down in my ear. ****ing disgusting. it is not my problem if they are on strike. sort this out. stop being *****. I HATE MTN, NEVER HAD SUCH BAD SERVICE IN MY LIFE
