Bad service

I'm an not happy with netstar the way that they are Billing me the are overc

hanging me and causing unecessary bank charges the product that I took was netstar plus which is R169 now they went to debit R2237 I complained to them last month hoping they would rectify the error but still again doing same mistake. The amount that expected them to debit is R212 now I have to reverse the money. This is daylight *******.
