D's Transmission & Auto Tech

Problem with vehicle never fixed. But repair bills totaling $686.00 were paid for repairs. With the problem ongoing.
I called D's Transmission and spoke with [redacted] on 1/8/13 and told them when I started the vehicle earlier, it was chugging and all the lites came on but it drove good to work. Upon making it to work smoke coming out of the hood. D's came and towed the vehicle. The next day they told me it was the Thermostat which would be $382.82. Picked vehicle up 1/11/13 and paid with my debit card once again smoking under the hood. Called D's they came and picked up vehicle. [redacted] from D's left me a voicemail telling me it was not pressurized and keep loaner car. On 1/14/13 they called saying it is an oil leak and that would be $303.04 and this will take car of the problem I am having with the vehicle. I picked the vehicle up on 1/15/13 paid with a personal check. I made it to work vehicle smoking once again. Contact [redacted] at D's and he tells me it will take 2 days for the oil to burn off the engine. This morning went to start vehicle once again all the lites come on and chugging same problem that started it all. My vehicle is still not fixed and when I contacted [redacted] at D's transmission he tells me I never gave him any of this information when I first called about problems with the vehicle. This is untrue I told him everything. D's Transmission has had me paying for repairs that was not for the problem that I brought the vehicle in for. I am out of over $685.00 with my vehicle still not being repaired.
