Unacceptable service

I have placed an order with Take a lot and my delivery date was supposed to be Thursday. It is now friday and I have not received any commuication from Take a lot. I had to call them and follow up after struggling to even find their contact number. The lady at a call centre told me that the delivery company only received one item and they cannot deliver it, They will have to wait for the other item. I dont even know how long will that take. Firstly- As a customer I expected a better commuication from them as they were aware that they will be delay with deliveries from yesterday. Secondly- The tracking on the website is not even working or accurate. This is such a bad experience for me. I have ordered goods with them and I have never had such a horrible experinec. I need to travel monday 16:00 and now I have to postpone my trip due to their incompetence.
