Poor service ! Sales ****

We have taken up a deal that was offered via their call center sales department on Black Friday 2022, to date we have not received the device nor did we receive any communication via e mail telephone call or sms to notify us of a delay . We have made several follow up call to their call center and still no one can give us an answer as to what is going on, all we get told is that there is no stock!. When we ask to speak to higher management, we get told they cant take call but will call us back, needless to say, that does not happen! How can you run a special and not have stock? And why have we not been contacted to advise us of this issue? . What is your customer supposed to do now? Just sit around and wait ...totally unacceptable!!!
