On 11-16-2022 I came in due to a "service battery charging system" warning light that turned on my dash the night prior. I verbally agreed to pay for diagnostics and needed service done promptly as I was late for work. The initial diagnosis was I needed to replace the secondary battery (charging at 11.5V) in my car for x dollars. I agreed to the service offered and waited. Later I was told my main battery was a dry type, charging at 6V, and I should replace it with a wet type which costs more. I agreed to that too. When my car was pulled out of the bay the warning light stayed on. The mechanic couldn't figure out on the spot and took it back in. After taking the car back in for further evaluation I went to get something to eat as I was there for 5 hours or so. I then received a call stating I need to change my alternator because the new batteries burnt it (not sure if the exact expression) and now I needed to pay am additional $462 on top of $739 I already paid for the batteries. I asked why wasn't that diagnosed first and got an answer the alternator may have been already weak or something like that. In the initial receipt it is printed I declined diagnostics which is not true. The lady in charge signed I didn't decline this service. This was added in writing but the print is still there stating I declined diagnostics, thus voiding the warranty terms as stated on the back of the invoice. So anything I authorized them in good faith is now turned on me and has zero warranty if they do wish. For the alternator the lady said she won't charge me for the labor, rather just the $462 for the cheapest she could find). I was given a verbal warranty it's all good for a year. No certificates nor serial numbers were detailed anywhere on a receipt or copy - I was told this only happens at a dealer store. Total expenses could've been my alternator $462 plus labor only. I ended up paying $1202. For this incompetence/unprofessional behavior I request to be refunded.
