The online help was excellent. Te battery was installed perfectly but the tech who installed it was incredible rude and unprofessional. He arrived and didn’t calll to let me know he was there. I saw he was there and when I came out he was on a personal call. When I approached he was unmasked and didn’t acknowledge me but just went to open my car door without asking me if that was ok. He remained on the phone and when I asked if he could get off to talk to me he said that he was a busy business owner and needed to be on this call. Clearly he wasn’t the business owner, and this was a personal call. No customer service whatsoever.
