RenewIt dishonesty

I recently had my car repaired at RenewIt Sandton. The service and repair was adequate, however, upon taking my car to KIA motors immediately afterwards I had discovered that a fuse had been blown and subsequently repaired, indicating that a jump start had been administered. This has voided my warranty and cost me a fortune to fix. This was the first time my car had ever been in for repairs since purchasing it brand new, therefore this can only have happened at RenewIt. Quite frankly, I am disgusted by this outrageous lack of ethics displayed by RenewIt. DO NOT USE THEIR SERVICES. I have reached out to them and been sent in circles with nobody willing to accept liability for the financial loss they have caused me. This company is dishonest and unwilling to take accountability for the damage that they cause. I. AM. DISGUSTED.
