False advertising

It saddens me to leave this review,however my husband and I spotted an advert from their preowned vehicles for a suzuki going for about R139k,we call to check for availability and they say yes its available,we head to the dealer,we test drive and we tell them we like it,we want it. We apply for finance through their F&I and she comes back with approvals,we pick the best option and upon arrangements for signing and delivery,they tell us the increasing the price of the car because they falsely advertised it initially. Long story short, they tell us take it or leave it, after all that trouble of driving there and applications with all banks.
