POOR CLIENT SERVICE

I have tried asking for a manager to call me or to be transferred to a call center manager but they kept telling me that he or she isn't available they are in a meeting so im not sure if they are sleeping in a meeting room until now still waiting for their call there is an agent who called me a Xhosa lady she kept me holding when i told her that i wasn't happy the way she kept me holding she said its not her fault so im not sure if Ackermans the shop itself is able to communicate with me and apologize she couldn't say im sorry i mean to take accountability because i believe when calling clients you be representing that particular company i kept asking her her name she refused telling me her full name i called the same day asking to be transferred t her manager i was told the same story that he is not avail he is in a meeting and he was going to call me back. their number is *** my number is ***
