Late delivery with no communication

I ordered the Tv on vodabucks store on the 27th of September and according to their disclaimer they deliver between 5 to 7 days but with my order it is different story. On the 5th of October I received an invoice showing me how much I have paid and the guy who delivered the Invoice promised me that the Tv will be delivered the following day and even today I have not received it. I followed up with them via email and this morning I got an email from someone saying that they can’t find my order. I am really disappointed with how they’re handling this because they are not even communicating I am the one who is doing all the follow ups.
