Mr Turbo Warranty

Mr. Turbo Boksburg. I overhauled my Audi A4 turbo engine and decided to get a bit better K03S turbo from Mr. Turbo. I was running in the motor and only did 500km then the new turbo started to smoke, (3 days before my warranty expired ) I took the turbo off and installed my old turbo with no problems. As it was a Saturday I phoned Christa and there was no answer to I left a voice note on the last day of the warranty. The report given to me was low oil feed so no warranty . I got everything new in my engine including oil pump. The phone was dropped as we were talking. I hade no noise from the turbo and they sent me a photo of the impellor badly scratched. I just wanted the turbo to be fixed and they do not warrant there warranty. Don't go to Mr. Turbo they will sell as fast as they can but don't depend on after sale serves.
