Lenovo — Faulty product - Lenovo Yoga laptop

Lenovo case number - [protected] In the first two weeks after purchase my Lenovo Yoga laptop started showing a fault with the touch screen. After calling the help centre I was advised to perform a factory reset which alleviated the problem of ghost touching for about a week. I called again and advised that the factory reset had not been successful and was told that because I purchased the unit in Australia and was now in Canada that I would have to send it back to the point of purchase and pay for all freight costs myself for the repairs under warranty to be made. I attempted to call an external registered warranty service provider in Vancouver where I am currently living and after they kept the unit for 3 weeks and did nothing with it I called Lenovo again. This time I was told that they could indeed fix it under warranty at their repair facility in Canada and they would pay for all freight. I was told the repairs would take 7 days. Once they received the machine I was told that the part would not be received by their repair centre for another 2 weeks. After 3 weeks had passed I emailed and asked for an update on my machine with no response. On the fourth week I emailed again and received a response that said the part would not be sent for another 6 weeks. I then received a call from a Lenovo rep who said my case had been escalated but any returns would need to be done in Australia, however, I shouldn't worry as an Australian rep would call me within 3 working days. Another week has gone by and I have had no further contact from any Lenovo representative. I want a full refund of all money spent which includes an anti-virus and windows package which I am unable to use
