Shocking service - dont answer calls or emails - dont deliver

I placed an order for delivery online on Thur 28 May 2020. The whole reason a person orders online is for the convenience. In 1 June I received a message saying that the order will only be delivered on 8 June (thats 10 days later) Thats just not acceptable. Id rather go stand in the queue at the liquor store or ask Pick n Pay to deliver. So I emailed asking for a refund - no reply. The directors email address bounced. I called a number which rang without answer. I called another number answered by a clueless person who transferred me to another extension which rang forever and then cut off. When I called back ... surprise ... they keep cutting the call because they know I want a refund. This is the worst service I have ever had and I will certainly not use them again. The only reason I even used the service is because a friend recommended it - well what a disappointment. I really hope I get my money bac****!!
