Poor customer service, fees increasing everyday year

I've received an email from Adt that my account is owing R698, I have replied on that email, asking for clarification on that amount, to this day none of the consultants ever called, I tried to call the customer care and I was told to contact my relationship manager, who holds my account, so the whole Adt staff members are not trained to do the job? I dont recomment Adt to anyone, i was called by someone by the name of Hardy Germishuys, the guy is very rude, and he told me am not the only client he's calling. Poor clients service. ADT is increasing their fees every year, no I cant
