Bad customer experience

I've been using net nine nine for 2 years now but from from the beginning of this year I've been having the same problem that somehow cannot be resolved, 1. They have added people that are have not authorized on my profile 2. They are debiting my Acc for those unauthorized people I've been requesting a credit for months to date I have not received the payment 3. Everytime I visit the outlet to resolve my the issue of unauthorized people under my profile it gets fixed for a week or so and they put them back to my profile 4. Call Centre is a nightmare almost 80% of the consultant I've engaged are Unprofessional and lack customer service skills that's including the supervisors My simple request is to be credited for all the months that they debited my account double, to create a stand alone profile and get the services that I am being debited for on a monthly basis
