Bad service from telkom

Dear telkom personal. Ive had problems with my exchange during evening time since ive gotten your adsl on Feb. Ive complained about this problem for months and about a month ago they finally admitted that that my exchange was congested and move me to anouther. When i received the phone call from a telkom call agent monitored my ping and same problems as always for those 3 days of me monitoring my line after the move. After then my line was perfect for few weeks untill 8 of june 2015. Im really disapointed in your guys service after thinking the problem was fixed with my congestion and really tired of phoning telkom to only getting help when threaten to go to consumers court if my problem not solved i will definitely go to consumer court for refund of all my months of subscription with telkom and i will move to an isp that actually gives a ****. Sorry for language im just tired with telkoms pethetic service im suppose to be plaing dgl that is hosted by telkom but my ping at evening is to high.
