Poor service

Went to Nissan Edenvale the one at cnr Aitken road & van riebeek Ave To replace my mirror, went straight to the gentleman who assisted me with the quotation Mr Werner Taljaard greeted him, he shaked his head as if I'm a nuisance never acknowledged me or greet back he continue with his for about 10 minutes. Went to the front to complain he saw me complaining and came asked what's the problem explain to him how unprofessional he is and he just told me to **** just that, I will never set my foot there
