Call centre want to force new pay plan and overcharge client with the phone calls

I as the customer is more than 20 years plus a client, that love my account and buy quality with you. As a customer, I'm really unhappy with the way Foshini group, are making money out of the customer. There were arrangements more than 3 months back, with email and by telephone. You keep on charge customers R25 for a phone call and a message, in month it is more than a R100 +

The client has a right to refuse to make new arrangements that has been done. Why after 3 months you keep on harassing me, as a client with phone calls and let the call centre decide what you should answer to make them happy and keep on charging you on your account. Maybe you should rather investigate why the customer is saying what she is saying and stop harassing for new arrangements to be excepted by a call centre person. According to law harassment is ******* and we as customers has customer protection as well.
