******ion by delivery driver

The initial address was incorrect. I spoke to the driver several times. He immediately wanted extra money. I then tried to rectify the address. It said the address was too far, but I then placed the same order to the correct address and the order came from the same shop, which means the system is faulty. The 1st driver refused and told me on chat. I wanted to cancel but was unable, driver told me to cancel. He then came to my house after I placed another order still wanting extra money. I initially said I would pay but he kept on demanding more.
