I referred business to Bidvest McCarthy Witbank in January of 2025 and up until today my agreed spottersfee/commissions on the deal have not been paid. The agreed amount on the sale between myself and McCarthy was R20 000 for 2 New Crafter busses. After the deal was concluded they said they can only pay R10 000 of the agreed R20 000, i was infuriated but eventually agreed yo that and STILL no payment has been made by them. This is absolutely unacceptable behaviour from such a large group!!!
