Colin Lotz and Allan Rosslee refusing warranty claim

<p>I bought the car as a demo model. It has a full service history but the 15000 service was not stamped. I do however have proof of service history. I took my car to CMH East Rand this week to check up on my car losing power after i took it for the 30000 service there. they picked up that my turbo is faulty. I then received a call from them on Wednesday saying Colin Lotz and Allan Rosslee refuse to approve my warranty claim because my book was not stamped. I even mailed my proof of service to Ronnie Cronje at CMH East Rand only to be told i need to stamp my book first before they help me because those two have refused. This is not acceptable at all. I have even gotten the branch that serviced the car to send me the invoice. I need this turbo replaced ASAP!!! Very dissapointed... </p>
