Not receiving my products or a refund

I am really disappointed with the customer service of HP. First of all, I waited two weeks to find out the order that I placed and PAID FOR is out of stock. In that two weeks I inquired three times about the process and status of my order and all I've got is "It is in progress". After waiting another two weeks for my order, they told me that they won't be getting new stock in. I asked for a refund and now I am waiting almost a month for my refund as well. I provided them with all the information they need but still I am waiting. I've emailed the head of customer experience, Lisa Busschau, yesterday (14 June 2020) and received an automated response which sates that she is out of office until 17 March. Therefore the response is out of date unless it means until 17 March 2021. I've called two office numbers of HP but both says "Subscriber not available" and I've contacted Lisa on her cell phone but also got no response. So people, please don't buy at HP!! They are taking your money but don't give you your product(s) or money back!
