Pathetic Company

I have purchased a bed from Mega Couch and Mattress at the Middelburg Mall on the 17th December 2018. I had arranged with the salesman that I need delivery to be made in Johannesburg on the 5th of January, which would be tomorrow. He had given me his contact details and advised me to call him a day before (today) to confirm delivery address. I have tried calling him numerous times this morning and it seems as if his phone is off. I have tried calling all the Mega Couch and Mattress numbers available on the internet as well as the number on the top of my invoice and all I get is "the number you have dialled does not exist". This is pathetic and is absolutely appalling that none of the numbers work. When will I get delivery of my bed? I have paid the full amount including the delivery fee, what kind of customer service is this????
