Pathetic customer service

I bought a Greencoil Sanctuary bed from Restonic on 7/10/2021. I was informed it will take 2-3 weeks for delivery. I haven't received any feedback on the progress of this proses. After 3 weeks I phoned and asked when will it be delivered. No definetly on the 4th or 5th Nov. I phoned again on the 2nd and asked if the delivery will take place as it is been 4 weeks then already and I need to arrange for someone to be at home. No it will be def delivered then. They will phone me and arranged a delivery time. No call received on the 4th. Today on the 5th at 12:00 I decide to phone again and asked what time as I need to make arrangement. The lady Lee Ann told me she will phone me back in 20 mins. After 2hrs I received a call from her, no they wont be delivering today. No reason why not or nor phoning in advance to tell me this. I told her this is unacceptable I need It to be delivered today. She laughed and said this aint going to happen. I was very upset and told her I neef to speak to her manager. She said he is in a meeting I can email him! I told her this is pathetic, I am the client and I was the one that needs to phone them the whole period to follow up and now that I need to speak to the manager I must contact him! She said she will asked him to phone me. Coen is his name. Needless to say I am still awaiting his call at 18: 15! This is not the first bed that I bought from then and the previous customer care was good but this will be defenitely be my last bed that I am buying from them. The customer service is pathetic and they really need to learn how to work with customers!
