worst service ever

what a worst service ever.their customer care service is the worst. will never use this company ever again.my deposit was paid on the the 18th April.i returned their car before the time I was supposed to return it.still today 2July still waiting for my money.and worse their contract states etoll's are kept on R250.but somehow mine came to 5hundred something. being asking for a breakdown down.but nothing. even worse their latest is my banking details are not correct.after this was supposedly fixed on the 14June. this is so unacceptable and not professional at all.
