Poor follow up customer service!

They originally paid for my total clutch replacement but when responding to their follow up message explaining I was not happy as the clutch was not done properly and to top it off other issues now arose! I have since sent 3 emails to a Lerato Aphane and just no response! I received an email to extend my policy as it was about to expire and yes after responding still no reply! The complaint is clearly being ignored as my policy was ending. Why email a client and ask for an update on the service received but not have the decency to respond back.
