Where do i start first claining for a braselit that was ****** and they saidbthey will phone me why it was declined still waiting

I bought a mictowafe and slowcooker together. Microwave was canceled because of no stock. Bought a new one and also paied with my account it was canceled showing my account payment did not go through(did phone them and it was confirmed the payment is done) but there was enough money to buy 5 microwaves. This was a gift to my sister as a wedding present. Phoning and phoning them before19h00 the leave me hanging on the phone after helping me to find out why i was holding and R150 worh airtime was used or rather wasted. Im discussted with them. Did got a voucher bit that do i get for all my trouble phoning them to find out what is goibg on. I bought a nother slowcooker on the 8th that was de*****d to a friend but still not hetting mine mut she is living 300 km from me and customer care telling me stock is comong from jhb really do they think im stupid
