Pathetic service

I placed an order on 24/09/2019. On 27/09/2019 i received an email stating that they do not have stock of 1 item and have allocated a store credit. They did not contact me to ask if i would like to take something else instead. Now i have to do a separate order and buy up til r400 in order to get free delivery. I have emailed them to credit my bank account and til today no-one has respondef. I received my order today 2/10/2019 and 3 out of 4 items was incorrectly labelled and would have to be returned.
