Unsatisfied Customer due to incorrect stock and price

Enterprise Ethanol/Enterprise Solvents is the most unorganised company. I called and spoke to someone is JHB and she confirmed that Cape Town has stock and gave me the price for Cape Town as well. She also advised me to contact the branch and I did that, they confirmed they have stock. When I arrived, there wasn't stock, and the website price is not the price they charge. I have had this issue previously and I am very angry with their customer service. The Cape Town branch is very useless.
