Terrible/horrible customer service

I called in this morning to book a bus. I spoke to a guy by the name of Phiwe Khumalo. He quoted a bus from Cape town to Pretoria that is R395.00.I had a voucher of R150.00.So he advised that I need to go make a deposit of R245 and send in proof of payment to secure the booking. So I did that and I called in again to confirm if email was received and the booking is done. To my surprise I was told that I paid short amount I was suppose to pay R270.00 as the bus is R420.00.Then I said that is impossible because I called in and I was told how much the bus is and how much difference I need to pay in when the voucher is deducted. So he told me that priced are subject to change. So Phiwe and Yolanda Vilakazi told me that they will send me the confirmation that the booking is done. I did not receive anything from them. I called in again and I spoke to Phiwe Khumalo again and I asked to speak to Yolanda but he told me that Yolanda is busy on the line, I said I don't mind holding. So I was on hold for Yolanda for about 15 minutes until I decided to drop the call and call and dial again. I then spoke to Nhlanhla Phile ,I told him that I am holding for Yolanda. He informed that Yolanda and Phiwe has gone home at 2h00.I was shocked because Phiwe said I must hold for Yolanda as she was busy on the line. He never came back to me to inform me that Yolanda is not available he just went home leaving me holding on the line knowing that they are both going home. Nhlanhla helped me to get the booking confirmation. What shocked me is the wrong information I was provided, that when I call in I hold for 15 minutes no one comes back to speak to me .So this makes me wonder if this is how the customers are treated by careless and *********** staff.
