aggreement broken and I am handed over.

Good Day,I am tottall upset and fustrated with Altech netstar+credit worx.Today after emails to credit worx I call in to explain my bad service and failure of aggrement to me my Netstar.My account was taken 2011 and my memory goes back now asa unit for r99 was suposed to be fitted ,when we left the vehicle for fittment the guy came back to us advising us another unit was fitted and we should come back to fit correct unit on that Saturday which went and the incorrect one was fiited will be cancelled asap as we did not want it,or it would be given at a discounted rate,only to see that the agents did not cancell or give the discount and the debit was going for an higher amount than aggreed upon with Tanju rajpal or Rampol at the sales dept for the Umhlanga fittment centre.So i called her and she kept advising she sorting out,i then moved branches and my emails were deleted,advising Tanuja that I cannot put up with this and she should cancel the service as they failed to my aggreement and in 2014 i spoke to an agent at credit worx he advised that he will refer to netstar to investigate again,agents did not get back to me until recently and today Icall them waitn for 30 min called 4
