Appalling service & Sabotage - VW Wonderboom

I am very disappointed by the appalling service that includes sabotage, abuse and disrespect that I have received from VW wonderboom. The management is very pathetic and absolutely unprofessional.

Taken VW Tiguan for 180000km service (the car has never skipped service and never had any technical fault) After paying R7599.60 for service the car started having engine light problems within a week after service, the problem that the car never had before.

Contacted VW service advisor and the car was recalled to be checked but the problem persisted, this has happened 4 (four) times the car being recalled and checked by the so-called technicians but could not resolve the problem and every time its pathetic excuses given without a proper diagnosis report.

Launched my complain to VW wonderboom management, there hasn't been any intervention/apology nor report to assist during the 4 attempts in resolving the problem. The car was taken for service on the 11 march 2022, recalled for engine light issues on (24 march, 06 April, 08 April and 14 April) and the problem remains unresolved!

I feel disrespected and sabotaged in that I have incurred additional costs on car-rental of about R14000 including being absent from work. How difficult is it to diagnose and sort out a technical problem on car with qualified technicians/engineers?

I am now considering trading in the car and get another brand (NOT VW) where I would be treated with the respect I deserve as a client/customer.
