Suzuki penta Brits branch

I am very dissatisfied with the service I received from Suzuki motor penta Brits branch. So when we made a deal for a car I asked to receiver at least 2 month cooling period buy because they wanted to make a sale they agreed and said even if the bank deducts they will pay me the installment from the dealership. The bank deducted on the 25th of September up until this day I have not received my momey. When I ask questions I am giving the round around. The manager is always not at the office and the sales person tells me that he will check and never comes back. So is this how Suzuki Brits deals with customers? Or I was promised because they only wanted to make a sale? Nobody is telling me anything so should I just give up on getting the money back? I am not happy with how you treat your customers😡😡
