Worst online experience

Where to start. First why do you have a process where I have to go into a store to pay for an online order and then go home. Wait and then go back to pick up stuff. I can just get the stuff right there. Who goes to a shop twice. That is not even the worse part. I want to cancel because like I mentioned I can just buy it while I am in the store. They cannot refund me. I have to wait for an email that might come in 24-48 hours. Then I need to provide my banking details? What for. You can cancel the credit card transaction. it is still pending. Their whatapp person just dropped the chat. So they have my money and I have no goods. The order is not in my online orders profile. They did not send me any email. only we received your order. Nothing about we can only continue after payment etc. USELESS PROCESS. something someone just added to say o we are online. I want my money back now!
