After Sales Service!!!

In November last year I enquired for medical aid for my parents. Spoke to Zaakir who offered me the Momentum policy. Got excellent service at the time. They requested bank statements and changed the option to the next highest level due R1000 being paid in my mom's account because they assuming it's a salary. Me and my brothers has an agreement and that is what we transfer to them monthly for food, electricity etc.. apparently that is Momentum criteria and nothing can be done. Alot of **** I personally think, in this day and age who earns R1000 per month, that's not even enough for food alone. After many emails, telephone calls they changed it but still not to the one I agreed upon at the time the policy was taken up. I emailed Zaakir to cancel the policy and up until today he has not rep****. Today the debit order went through my dad's account again, last month the same thing happend and noe his being charged unnecessary. Firstly you cannot just changed things as you wish without the clients consent and you are not allowed to take money from the account if it was not agreed upon. That's is ***** and it's *********. Please sort this mess out IMMEDIATELY
