In breach of the CPA

This must be the worst online shopping experience I have had to date. I purchased some items from @Home online and for the first time ever, I selected to use a Pargo pick up point instead of having it delivered straight to my door. Not being aware that this carried a specific deadline for collection, I went to collect the parcel and was then told it had already been sent back to the warehouse. Please note that this was on 27 September. Fair enough, my fault for not reading the fine print, but okay, no problem if it was returned, I just need to now figure out next steps, or at least that was my thinking. I then contacted TFG customer care to query what the next steps were as I hadn't realised that the parcel would get returned. I was then told not to worry, the refund is automatic and it would take about 10 working days for this to happen. Again note, that this meant, I was already passed week 1 of said refund timeline. Fine I thought, no big deal, just wait another week. The 10 days have now passed, I call again to query my refund. I am at this point advised that the parcel hasn't yet reached the warehouse, even though, on my profile for this particular order, it shows at warehouse. I then get a call from the courier who asks me if I collected my parcel. I explain that I did not and was advised by the staff at the pick up point that it was already sent back to the warehouse. He then says, okay, please follow up with TFG if you haven't yet received your refund. The following week, I have 2 or 3 missed calls from Pargo. I call back, only for them to ask me the same question...did I collect my parcel?! This clearly highlighted that the parcel had been lost, but instead of somebody advising me of this, TFG instead tells me that I can only get my refund once said parcel has been returned to the warehouse. It is now 5 November and I am still fighting to get MY money back, for a package I have not seen or touched. The fact that the parcel had initially been lost...NOT MY PROBLEM. The delays in reaching the warehouse...ALSO, NOT MY PROBLEM. The money not being refunded that I paid for the items not received, IS MY PROBLEM. I have followed up with numerous emails, same response received each time. "It must be received by the warehouse before we can refund you." Why? Why am I the one left waiting for money I paid to you over a month ago because your courier service stuffed this up? I have asked for this to be escalated, to no avail. I get the same responses each time. I appreciate the numerous apologies received for the inconvenience caused, but can I please have MY MONEY REFUNDED????
