Over charging elderly clients for services

I called the called center to reconnect my mothers services. They informed me to deposit money and the would reinstate the services. I did as I was told and submitted proof of payment. Next payment was said to be due on the 27th Dec 2022. Services were reinstated for 2 days and now they have been disconnected again. When I enquire I'm informed to make additional payments for the services to be reinstated.

Same thing happened last year. We are being conned and its only the elderly that are affected
