DOUBLE CHARGES NOT BEING CORRECTED

Good day. I am a bit disturbed at the amount of times I emailed MTN with response emails and some of my queries have been attended to and others not. The problem is I have 2 phones on the account. BIS charges were still being charged, some now reversed. Insurance is double EVERY month. CLI double EVERY Month. I am owed a huge amount due to this and this is not getting resolved. Still double charges. PLEASE ATTEND TO THIS ASAP AND EMAIL ME. Tonight another debit order goes off my account, which will be incorrect. but if I reverse it, my phone will be cut, so you cannot win. Requiring urgent assistance and only reply by email.
