Worst Service Provider

Ever since Nashua Mobile closed shop last year and subscribers were moved to their respective network, i have received no joy from MTN. Since last month i have called every available number on MTN to get my itemised statement for March(February usage) almost every week because i was not able to download it from MTN Active account like i normally used to. Each time i call it's either i can't get thru the call centre as they always busy every day or i will be transferred from one department to another after holding for more 20 minutes. If i'm lucky to speak to someone that sounds like they will assist me, they advise me statement will forwarded to me within 48 hours. We now in the month of April and i require both my March and April statements as i need to claim for my business calls and not even one person has ever called me back , the only thing i get is an automated email reply advising that they are aware of my query and will be attended to but to no avail. I was given 2 reference numbers and i'm not sure if a case was really logged on my behalf, 1st one is *** and recent one is ***0 that i obtained from Mphela Teffo who had advised i will get my statements within 48 hrs.
