CAME BPT no after sales service

Very disappointed. Made an appointment with Shaun. He never made the booking. When we arrive at the Came for appointment it turned out it was never made. Shaun claimed we gave him the incorrect email. Problem is it is not even remotely close to our correct email which they have on their system and even if he use the mail he claimed he got it immediately get a 'return to sender' reply. He never phoned me nor technician (both numbers where left) to follow up on correct email. When I complained to branch manager Andre, he said he feel protocol has been followed and we should sit around a table to get it resolved, there is nothing he can do. No apology, no acknowledgement of mistake, no client service.....
