Will try and keep this short and try not to drip feed.
Bought a new car last year. Salesman used my phone number to arrange a few things to do with collection etc. Fine. Though, unbeknown to me at the time, he was using his personal number.
Fast forward a year and I get an email reminding me my service is due. Also fine as it saved me the trouble of booking my car in. Once again, used my phone number to arrange things for the service such as dropping off courtesy car etc.
The salesman was really helpful, as I was on crutches at the time, and the service was great. I expressed this but definitely did not give him the 'come on'.
He has subsequently been sending me messages not to do with the car and which I find really inappropriate. I have been polite as I need to keep my relationship with the garage as I have a service plan but I'm really not comfortable that he's got my mobile number and is now using it to offer me a massage and to ask me to send him a thank you card. I am sure he's breaching GDPR as well.
So AIBU to complain? I called him out on it by saying to him he had a partner and he denied it. He does indeed have a partner. I definitely have never given him any intention I like him that way and I went with a male friend to buy the car who he thought was my partner.
