Absolutely terrible communication

I placed an order online on the 21/05/2020 for one item. I didn’t immediately receive a dispatch date of the order so I emailed. A person working for Karibaa informed me that the warehouse would let her of the dispatch date.

I then received an email informing me that the item was out of stock and they could either refund my account or give me the alternative item they had on hand. I thus chose the alternative item and let them know of my decision on the 24/05/2020.

Since sending the email informing the company that I’d like the alternative item, they have not come back to me, even after I had sent numerous emails asking about the delivery date of the order.

The number provided is off and my emails go unanswered. The lack of customer service is sickening.
