Very disappointed

I am very disappointed with Bash, I bought 3 x takkies online and the one was canceled because apparently they didn't have it but I saw it online. Nevertheless I was given a voucher for the inconvenience, to my surprise the voucher don't work online when I called Bash online one agent said its for the store after I waisted almost 30 minutes with her online and she had no clue was she was doing. I went to Musgrave store I spent another 45 minutes trying to sort out this voucher and called Bash online again they said its for online they will investigate why its not going through, I had to leave my 3 pair's takkies in the store. Now I have bought and lost out on that voucher number.
