Debit order misused

Good day<br> I've been a client of ADT for many years, never had problems. Last month my account was debited with an additional amount after my monthly premium was already taken. I queried this with ADT and it took them 3 weeks to actually notice on their bank statements that I have paid the alleged amount a month ago already via EFT. Multiple requests by me to have them phone me has been ignored and I had to email many people with my proof of payment to get my point across. Every time, it's someone else I have to email.<br> Yesterday my ADT premium was taken at R585 (2 Dec). It's normally R329. This amount of R585 is not even double R329. I've received a statement of Tshepo Ramasala last week, indicated that ADT owes me the R148.20 they took off my account via debit order without permission, so by all rights, i should only pay R329-R148.20= R180.80. Because that's how I understood the statement.<br> So please tell me, again, why am I paying R585 this month?? What services did you give me to amount to R585?? I wasn't aware of this, no invoice was sent. I was given my statement only (I had to ASK FOR IT). Answer your phones!! I've been holding on for 10min and nobody phones back. REFUND ME!!!!
