Poor customer service

I bought a soundbar in special at house and home online on 01/12/2025, enquired and was told they’re out of stock by email. Tried calling them to hear the estimated date of delivery and even today haven’t gotten hold of them and calling every day. It irritates to pay for something and not be clearly advised as to when you will receive your product for your hard earned money. Why don’t they even answer calls atleast? Let alone advertising products that they don’t have
