No support from Castrol!!!

Had a mitsubishi 3,2diesel in for service, Transmission oil was low, checked with my supplier autozone and the checked there castrol catalogue and supp**** me with 500ml recommended oil Added oil according to castrol Catalogue, customer went home called castrol and castrol told him it was the wrong oil, customer requested me to pay R1870 for a complete transmission oil replacement due to the info from castrol which i did, Autozone called there rep and he said he will sort it out but never heard from him again, autozone called again castrol and was told by a manager to fax copy of catalogue, we called again and where told to resend the fax but no reply from than on, autozone called again and was told rep will come, this is now over two months and i have no answers or a refund from either Castrol or customer, besides i think by Castrol delaying it for so long my customer would have already unnecessarily replace his transmission oil if castrols catalogue is correct!!!<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br>
