Worst customer service ever

I have placed an order on the 26 of November and up until today have not received my goods. I have phoned emailed and used the online chat facility. The support staff is useless and keeps on stalling by telling me they are investigating. Poor poor customer service. Eventually I got 3 emails asking for my delivery address for delivery which I immediately forwarded to them. The delivery was supposed to happen Monday the 13th. Nothing. It is now Thursday. No response despite emails being sent. Unacceptable. I have never experienced such a low quality of service.
