Pathetic Service!!!!!

I have been a contract customer with MTN for about 20 years. I recently have had terrible service. They suddenly decided to remove a discount that i got throughout the contract and charge me extra. when I queried this, I will told it will be investigated. I spoke to several people in between to get an update on this. I eventually spoke to Jabulani who was quite helpful. They has suspended all my lines just for the 1 line ....He said he has logged another query and activated my lines. Yesterday I got suspended again. When I called I kept getting told their systems are off. Eventually at about 4pm I spoke to Nomfundo Sithole who said she cannot activate the lines due to this "queried amount of R295" being in 60 days. I explained that MTN needs to sort this out but she was not able to hep. She then put me through to a manager named Lelisha Ramthol who asked me to send my current proof of payment of my current month premium which i did and to no surprise when I called back, she had left. Eventually spoke to another lady who assisted me .

MTN is this the service you are now offering. Do you totally disregard your clients that have been so loyal to you for so many years??????

I want this issue resolved urgently!!!!!
