Need Refund please

I bought chairs online and opted to pick up at store. I got a call from the store the same day to inform me that I could go pick up the chairs. When I got to the store I was given receipts to go pick them up at their storage, 4km away. When I got to storage they couldn't find the *****s for the chairs, said they'll get at the store when they knock-off...we agreed to meet at the store after work. There were no *****s at the store either,I got worried because I needed the chairs 3days later latest to set up at a business office. They tried to get from the local builders express but couldn't get the correct size (took them 2days). I decided to call customer service because I had less than a day to get the chairs or replace them, they unfortunately don't handle online orders. I was given an email address, I requested my money back cos I had to get new chairs the next day. Nobody is responding to my email.
