Poor customer service

I was contact by a consultant from sell direct offering me a good at the time of which I was interested and opted for the deal. I then recieved an sms 2 or 3 days later with the waybill number of my parcel that was going to be delivered by a company called courier it. I spent an entire day from 8am till 5pm for the phone to arrive, I made numerous calla to the courier company to find out what had happened or when the phone will arrive no one really got back to me only once I arrived at home someone called me and the advised that the parcel had been hijacked of which I understood and was not upset about as these things can happen in today's life. I then waited a few days and no one made contact with I then called the courier company again of which they advised that selldirect will have to provide a replacement. I then contacted sell direct and the lady advised me that no one had placed the replacement order and she will be doing so immediately, I advised her that I needed the phone as it was for a Christmas gift and was assured it will be available by Monday the 24 December 2018 and I will collect it at the courier as I'm on road as a rep. They advised they will be sending me an sms with the details and a new waybill number of which never happened, I waited again a few days and on the morning of the 24 December 2018 I called selldirect again to find out whats happening with my order and was told by another lady that they will contact me within the hour which was past 8am when I called, it's now 22h35 on the 24 December 2018 and many hours later and still no call. Such poor and pathetic service this company might as well close down because you clearly do not understand what is customer service even if you not able to provide me with a solution atleast make contact with your client and keep them abreast with what is going on with their query. I genuinely regret dealing with your company poor poor poor very poor service you make me sick to my stomach. Tomorrow is Christmas and you could not fulfill your service deadlines very bad. Please close the doors of this business it's useless anyway.
