Driver's attitude and no reply to complaint!

Yesterday I sent a message to Unicab via Facebook messenger with a complaint about one of their drivers. They have not yet ready it. So it seems like their Social Media is just as bad as their driver's behavior.

The message I sent was as follows:

Hi there. I would like to make a complaint about one of your drivers. I stay in Alexander Road, Sea Point, Cape Town. I went to the shops yesterday and came back with a car load of shopping. There were two of your taxis parked outside my house. I asked one of the drivers if he wouldn't mind moving, so I could park outside my own house, as there was parking a bit further down. He was just there sleeping while waiting for a fair to be called in. He looked at me and blatantly said "NO, This is public parking." Yes it may be public parking, but it is also a residential area. It is also not a place to be sleeping on one's car. If this is the attitude of your drivers I will certainly never use your services or recommend them to anyone. I will attach pictures of the driver and cars. Thank you. (Pictures were attached)
