Disgusted

Good day Last year October 2020 ADT contacted us constantly we eventually took their services on, well it worked ounce the next day when tested but never again worked . I have requested a response from managemant and Johan the sales Rep for my area since 14/12/2020, but almost 3 months later no response. I am now been asked for payment WHAT CAN I DO. They just do not care for their client service.
