Terrible Service from staff

I've had the worst headache of my life for the past two week, as I've been trying to by a car with WeBuyCars, I've had to change between four cars as every time I picked one, they would process the documents and later told me it has been bought by another person.The last car I tried getting from Nelspruit, I was told that finance has been validated, waited, called like more than 10 time to proceed with the next steps without any luck. I then eventually was told that the car can not be financed as it is strictly cash, something that made me to panic thinking that I might be schemed eventually, I still do as I have sent them all my docs. Finally the stuff that I encountered doesn't really care, as we speak I have 5 different WeBuyCars staff cellphone numbers and not a single one could help...
