Tecumseh Auto Spa

I had my oil changed at Tecumseh Auto Spa on Wednesday. It cost $ 158. On Sunday I tried to use my windshield wiper fluid and it was empty.
I checked my bill and amongst a number of FREE items was «top off» the windshield wiper fluid. Other free items included «Free Top off»:
anti freeze
Transmission
Power steering fluid
And a number «inspected items».
As I have a 24 hour round trip coming up this week, I went back in to confirm the rest of the work on the contract was done.
I had the manager/​owner come to the counter and discussed the issue and he brought into lube bay to discuss with man running lube bay.
He told us that «top off» meant a five second splash of washer fluid. I told him that isn’t the definition of «top off». He wanted to argue the definition. I told him I was not here to debate the English language with him. And he might want to look up the definition.
Even the owner said“top off means filling it to the top”.
I asked him to show me what he did for other «free top off» items. He showed me he just checked the items but did not «top off». I told them I am done bringing my three vehicles there if they cannot stand behind the contracted language of work performed. I told him it should say «checked not top off».
Owner then started yelling at lube bay guy about his bad customer service.
Lube bay guy then says «he has tried to get head office to change the wording on the contract».
I tell him now he is making excuses.
Owner is now screaming at the lube bay guy saying «you cannot treat customers this way». Lube bay guy says «I was accusing him of stuff». Owner yells «he hasn’t accused you of anything. «
I hand back the free car wash coupon and told him I am done and wouldn’t accept free work from them.
I left as owner and lube guy engaged in a heated argument.
You CANNOT TRUST their work.
