No Feedback - Loss of documents

I handed my TV in for repairs on the 7/2/16. My TV is still under warranty. I was told when I purchased my TV that all extended warranties would be kept online. I was told I would receive a status update during the course of the week. I received none. I tried calling several times, there was no answer of the telephone. Eventually I had to go in physically. The manager promised he would call the following week with feed back. Still no contact made to me. I had to go in physically again and was then only told that they could not find my Extended Warranty online. If there was contact it would have saved me the trip. I eventually managed to find the physical copy of my warranty document, I emailed this in on Monday (29/2/16). I have still not received any correspond regarding my TV. I am tired of trying to phone and going in to the store. It was been about a month and more than the promised 21 days and I still have no TV and have not had even a single correspondence from HIFI Corp.
