Pathetic service - clearly don't want to do business

I have on a number of occasions over the past 2 months tried to get hold of Goldwagen at Bellville, Goodwood and Claremont. I have tried calling and every time I get to number 1 in the queue I get cut off - except for this morning when someone at the Bellvilel branch answered and was shouting at me that he can't hear me because my line it bad and then put down. I find it very strange since my reception was 100% and I have had no other problems at all calling today. I have tried their whatsapp channel and have yet to receive a response after 4 hours.
