MTN does not care for their Loyal customers!!!

I have been a loyal customer of MTN for about 11 years now.I have always paid my account on time.Just Recently i went on maternity leave without receiving any salary.Little did i know that i wasnt going to get all the UIF money that i hoped for and then unfortunately my account got behind for about 3 months,because i could not keep up with all the costs of the new baby as well as all the other debts that had to be paid.I tried making arrangements with MTN calling the customer care line.I always had to wait for up to 20 minutes for my call to be taken and then the one time the person that helped me gave me an amount that has to be paid extra every month on top of my monthly instalment.I did what he said and then a month later my services got suspended.I went to the nearest MTN with the bank statement showing where i paid that extra amount but they just lift their shoulders and say sorry they cant help me because i dont have a reference number for the call.....even tough i had proof that i was paying extra every month,but Everytime there was a hickup in the arrangement made.My account was handed over to the legal department and services suspended...I finally got the funds to pay my account and sent through the proof of payment but after 3 days....still no service.How long do i have to wait??? They are quick to sell a contract to you but they dont care for their loyal customers when in a bad situation.and everytime a query is logged,the customer has to call the call centre everytime to find out whats going on....MTN should call us and give us an update about the query that was logged.I cant even make outgoing calls....how am i supposed to call them. The Tax recently went up with 1%. and MTN did not even notify me that my monthly instalment will be going up.I had to find that out from the call centre agent that i have been making short payments.I am really disappointed !! This will be my last contract with MTN service provider!
