Delivery **** at Kasyies Discounters

I bought a washing machine from Kasyies Discounters and I was offered delivery to Mamelodi at a fee of R350. The distance between the two locations is a 25min drive. Today is the day of delivery and I'm told to top up the money because it's far. Why was I not asked for my exact location on the day ?????? Why am I being asked for more money on the day of delivery???? This feels like a ****!!!
