Extreme Delayed Repair/Lack of Feedback

So about 8 - 10 weeks ago I took a Xbox One Controller(Red) into the Tygervalley branch(where it was bought) to have it repaired(as it was still under repair Warranty), as the micro-usb port was no longer working and made no connection when plugged in.

About 3 weeks later, I was informed the controller was sent back from the repairs department. The repairs department INCORRECTLY noted that there was nothing wrong with the controller.

After heading back to the store, and testing it in store with one of the gaming/tech guys at the store, alongside a working controller, it found that the problem still existed on the controller, and that the repairs department did not test for the actual issue on the controller. The problem with the controller was further detailed and sent back to the repairs department to have another look at it. Since then I have had no feedback(about 7 weeks), and after multiple calls to the store where I was just informed that they'll follow-up with the repairs team(again, no feedback from the store either following this) I have yet to receive any constructive feedback on the issue. When the controller was sent back, I explicitly stated that I would need it back before 27 October(which is a reasonable length time, I would think) to which I was promised I would definitely get it back within 4 - 6 weeks maximum.

After calling the store again today, and speaking to Emilio(whom I've been dealing with the majority of the time in regards to the controller) I was informed that repairs is still sitting on it, and have yet to provide him with feedback.

As stated in the store when it had to be sent through to repairs after their incorrect first evaluation; this controller was a gift for a friend. Said friend is emmigrating to Denmark and is flying on the 27th of October, which is why I placed urgency on the repair when it was sent back to the repairs team, because they didn't check the full state of the controller.

We need to come to some kind of agreement here. Whether it be a refund or a new controller in return. I find it ridiculous that I've been waiting for more than 2 months for this repair to happen, with absolutely no feedback regarding the issue or the holdup(despite all my details being on record at the store).

Would you kindly provide urgent feedback.

Regards, Simon.
