Intercape - Worse bus ride every

On the 23rd December myself and my husband and daughter drove from Amanzimtoti tot Pretoria with Intercape. We drove in a Main Liner. Everything went well at first the bus started to fill up to capacity and to make things even worse, there were cockroaches on the bus. For the whole trip which should have been 10 hours it was 12 hours. With a 3 year old needed to go to the bathroom they have stop only once and the bathroom on the bus was unusable.
