HTC Flyer sent for repairs on the 6th of February 2016

I took my HTC Flyer for screen replacement on the 6th of February 2016. Today marks the 19th month since I took it there. I have called a number of times and the response is that it is with the lab. I went there towards the end of last year in person. The owner told me he will be going to Hong Kong and will come back with the parts. Needless to say, no feedback was given to me. I have been calling since the beginning of the year and each and every time I am asked to leave my number and they will call back. They never do. I called in today the 5th of September 2017 and demanded to speak to the owner. I could hear him on the back round telling the lady who answered the phone that she must tell me he is on the other line and will call me back. Such disrespect for customers is appalling. I want my Flyer back. If it means I have to go to the small claims court or to the media, I will definitely do that. I am trying my best not to go there in person because I am not sure what is going to happen there. The lack of professionalism in that place is shocking.
