BAD SERVICE

My problem is with MTN as i have upgraded my contract in July 2015 all i have been getting is chaos.<br> <br> I am currently on the top up contract of which i pay R251 on the 25th, in October i made a late payment on the 30 instead of the 25 as i have changed my bank details, so i paid R300 because i was using an ATM then on the 12 Nov my line was suspended without any warning i called in to sort it out with there consultant Sakhile Qeqe whom promised that this problem wont happen again on the 17 Nov it then got suspended again i then called in numerous times from 09:29 spoke to Mbali Ntuli and a few consultants whom couldn't assist me so i then went to lakeside mall at MTN they advised me to call the 808 i spoke to Phumezwa Zazini whom took 45min totally clueless until i asked to speak to a supervisor then she placed me on hold for a while then came back to unsuspended my number without any apologies.<br> <br> On the 28 Nov round about 3am my phone was ****** on Sunday and Monday i tried calling the client service from this number *** the phone kept cutting me off then on Tuesday i went to MTN store in Oakfield Benoni i was advised that they cant blacklist my handset without getting a case
