Lexus

I went into the Lexus dealership on 9/3/19 for a diagnostic, I ended up needing a new hybrid battery on the phone I was told my total would be $3690, when I went in to pay for the part again I was reassured that my total was $3690 we spoke again on the phone a few more times after that and I kept asking how much the total was & multiple times he reassured me the total was the same. When I went to pick my car up 9/7/19 he just so happened to leave out the taxes... How, when multiple times I asked what the total was, having to already borrow $3600 from a family member is hard, try asking for another $400 last second. Your employees should not leave out such an important thing, after spending $4058 & not the $3690 like I was told, I'm just really upset. This should've never happened. I should've been told the exact total from the get go.
