She didn’t have the GM multi-point vehicle inspe unhelpful, hard dealing with, Inconsiderate, bothered her when asking questions I didn’t understand. She didn’t have the GM multi-point vehicle inspection sheet available, I had to ask at 2 other counters for it and I went back to ask her again. Id asked for a call upon vehicle completion as Id left the property; she didn’t call but said she did (I have no Record of her calling cell or Home phones. which is 80-Miles away fm dealership). In 5–3/4 years we’ve always been treated very professionally, this is a first for unprofessionalism. More

If I go into the service c everything in detail. Him and his twin brother Nobu are both very professional. They have been sitting together forever. If I go into the service center and don’t see them together, I get worried. Just a little joke between us but, if u would like to mention this letter in the morning meeting. That’s ok.
