Unhappy customer with Fruadulent billing & dishonest ADT Staff

I pay ADT fees annually a year in advance and have done so for past 8 years. I had 3 break ins at my place in Sandton over this time that was not identified by ADT sadly. Since 2016 ADT attempted to add additional costs calling it excessive call out fees. This is highly contentious as I don’t get refunded for the 11 months when there is no call outs. I challenged the call out and was refunded in the past. Again in 2020 the same **** started again trying to extract a monthly fee over and above the fee paid in advance.We are being bombarded daily with SMS stating we are in arrears and need to call ADT and Vincent Maludzi to make arrangement to pay. I called daily but the calls are never answered.One lucky day 3 weeks ago,Vincent called my wife while I was at home and I took the call. I explained that I pay a year in advance and that I am unhappy with the excessive call out fee ****. He checked on the system and confirmed that I paid in advance and my next annual payment is due only in July and apologised for the incorrect billing. He then promised to cancel the excessive fee payment which was unwarranted and not accepted. I requested him to send an email as proof of conversation which he promised to do. I am still waiting for his email 3 weeks later and then we get bombarded with same sms messages again. I am very upset with Vincent and aware all calls are recorded at ADT and request a copy of this recording to contest the outstanding payment allegations. I have tried to call the same *** and there is never a reply. A very unhappy customer who wants to now cancel due to dishonesty of ADT Staff ***
