Neglecting clients

Worst client service ever! My car got evaluated at Silverlakes branch 16 January, I was promised an email of the evaluation and I still have not received it, I did an enquiry on a car 19 January, I got a call back, gave all the details asked, did not receive feedback, did another enquiry on 25 January got a call back, they asked for my no. and said they will phone me back "just now" right after i said no one has contacted me or sent me an application form or anything and no one has phoned me back, even sent a WhatsApp to the one sales person, who is not responding.. I have never felt so neglected! Worse service!
