Terrible terrible service!!!

Is it possible to please provide customer training for the staff at the Braodacres Steers. I have repeatedly received bad service from their front of house staff. The only reason I am now bring it here is because it has now gone to another level of atrocious. I called the Broadacres branch to place an order and after the phone rang repeatedly over and over and over - Prince answered and said he was trying to call a client and I should drop and call back...EXCUSE ME! When I asked him why he didn't assist me then since I was using my airtime to call and he can proceed to his client, he put me on hold and then deliberately dropped the call. I was shocked! I called again and again and again and the phone was later disconnected. This is after 2weeks ago we went to buy Panda meals for the family and were told they don't make milkshakes before closing time ( this was maybe 20min ) as they had to switch the machine off. So we were told to replace the milkshakes with cooldrinks and pay an extra R20.
