Engine Doctor Sucks

I had my vehicle engine rebuilt by Engine Doctor JUL 2010. I got the vehicle home and noticed it was dripping tons of oil. I took my vehicle into my local mechanic and he told me the transmission dip stick tube was cracked; cracked when Engine Doctor replaced the engine back into the vehicle. Instead of messing around with driving the vehicle back to GR I decided to get the tube fixed and paid for it out of my pocket. The vehicle went into the shop a second time and at that time they noticed anti-freeze leaking which turned out to be a cracked thermostat housing. I called Kevin at Engine Doctor to see what he wanted me to do (have engine doctor fix it or my local mechanic). Kevin said to have the thermostat housing fixed by my local mechanic and he would reimburse me - well that was 29JUL10 and its now 18AUG10 and I still have NOT been reimbursed. I have made numerous calls to Kevin but he NEVER returns my calls. I was told three separate times the check was being issued but never was. Today I drove to Engine Doctor and talked to the person who cuts checks. She called Kevin to see what he wanted to do then she handed me the phone. Kevin started screaming at me and told me to F'n get off his property and to stop F'n badgering him for MY reimbursement - YES, he used the F-word against me as a customer - no lie. This also is no lie... for all the crap I have been going through I NEVER raised my voice or made any sort of threats I have just been calmly asking for my promised reimbursement. BEWARE...NEVER DO BUSINESS WITH ENGINE DOCTOR.
