No communication store or call center

On the 6th of April I Loged an incident with your call center, ********** 923, and they closed it without contacting me. on the 11th of April I mailed customer care, no response. on the 15th April I visited the Fourways Branch, empty Promises On the 20th April i called the fourways store manager, more empty promises. You have upgraded my account without my permission, have double and trippled billed me respectivly for March and April. Is this unfair recourse due to taking your call center to court for ***ist and derogatory remarks? I thought having a call center agent refuse to help me as I sounded like a girl was bad. If I knew you were such a vindictive company I simply would of ended my business with you instead of trying to find a resolution and continue doing business. I want a resolution or at least for comunication to take place between us both.
