Terrible customer service

I purchased a product from Technopro in July 2017. I used it twice and it became defective without any improper handling. I called and notified them of the issue on the 26th of September, I was told to log a request for return which I did the same day. I was then called by a manager and told that I should try and fix the product myself. I was unable to do so without stripping it completely so I called them back and asked them to arrange collection. On the 27th I was told a courier was being arrange to collect the product. I call them on the 29th and was told the lady who had dealt with me was out sick. I asked why the manager I had spoken to could not find out where the courier was and I was told he would call me back. He never did. I then called again on Thursday the 5th and spoke to the manager and was told they would call me back on Friday. They never did. I called again on Monday and was told by the manager, via a call agent, that I should courier the product to them to get them fixed. I said I had already paid for delivery and the defective product was their responsibility to fix or replace. They then asked me to forward my e mail correspondence with them so they could try to arrange it. We will see if anything comes of it.
