Netstar services cancelled, yet deductions are still occurring

I am writing this review for my 75yr old mother, who has made numerous efforts to email and contact Netstar regarding the termination of their services to her. She has requested since last year August that they stop deducting from her account, yet up until today they are still deducting. My sister even arranged a telecon between Mom and Netstar, and they came to an agreement not to deduct funds from her account, yet it is still happening - 6 months later. We have made numerous appeals to them for assistance but have received no joy up until now. This has been a very exhausting exercise and experience, and as a family we are appealing for some help as we are just not making any progress to move away from Netstar.
