Long standing Issues With return

I am honestly not even sure If this is worth writing anymore because I have been given the run around so much that I actually gave up on this matter. But I feel that this needs to be looked at because it's really unfair that customers can get treated this way.

In 2017 I bought an external hard drive from Makro Online. Less than a year later I wanted to return it as it was having issues in operation. I logged a return a few times on the website with nobody ever getting back to me. I eventually started sending emails to Makro online and again I got zero responses. I was then called a few months later and I was told that I will be assisted with the return (this was now 2019) I have still not been assisted and I really feel like this is unacceptable. I have all of the emails I have sent and received regarding the issue but no call records. I am really disappointed in the way I have been treated, especially since the website has changed, there are no records of my purchase apart from my emails.

May I please get assisted with this issue
