Mattress Warehouse non-delivery and poor customer service

On the 11th of February I placed two orders separately, because it showed on the Mattress Warehouse website that the beds were in stock, but the pedestals were not and I need the beds urgently. Therefore, I paid two separate delivery fees which were quite expensive. On the 12th I received a Whatsapp from Mattress Warehouse that I needed to send through the proof of payments. This after, I immediately received the proof of payment from Paygate on the 11th and then an order confirmation from Mattress Warehouse. After a week of non-communication, I asked when my beds will be shipped, when all of a sudden, one base and the mattress protector was not in stock (17 Feb). They have to order it from another warehouse. This is now the 1st of March, to date I have not received anything from Mattress Warehouse, the call center is not answering, and no delivery date has been confirmed.
