Unhappy customer

Hi there. I don't know if I'm writting in the right place. I have a problem with MTN, I have two contracts with them and sometime in December 2017 two more contract were added onto my account I knew nothing about them and I never received any notifications about them. I only knew about them when my payment was going through on the 1st of February 2018, instead of deducting R228 they deducted R2163 so I called 808 to find out what was going on so the guy who was assisting me asked me about my phones I told him I have two so he told me that in the system I have four lines that's why my payment went up. I told him I knew nothing about them and I asked how do I rectify that cause I really have nothing to do with those lines. He said I must send him the certified copy of my Identity document and the affidavit stating that they are ***** they are not mine. I did that one the same day 01-02-2018, he gave me the Ref no of the call ********** 88, he told me that ***** department will cantact me within 7 days they never did, I called to find out how far were they, I was told to wait then I waited and I never received any thing from them, instead I received an sms with the higher bill I didn't call them about it. I only called to ask about my own bill of my two data sim card and I paid it. On Monday the 5th of March 2018 my lines were suspended, I called 808 and ask why they told me about the bill that i didn't pay so I then asked the lady what was going on with the query of ***** that I made she said the was nothing on the system my query was never escalated, she asked me to send her the documents I did send her, she also never escalated the query,ref no ********** 19. Following day I called 808 again spoke to another lady she also asked the documents I sent them again and she also never escalated the query ref ********** 94. I called again yesterday the lady was trying to help but I'm still waiting to see if she really did escalate this matter. If 808 cannot help me where else my I call? Why are they so ********. I feel like crying as i write this. I have been with MTN for 10 years this year I never had the problem with them but this makes me hate them, I never skipped not a single payment now for being this loyal client that I am I'm receiving this disgusting service. Hope I will get help. Thanks
