Disgusting customer service

I bought a desk fan in December of 2024 and as we all know it's hot so you use the fan more often, which was no problem fan is working. On the 7 March 2025 less then 3 months later this fan don't want to go on any longer. I then booked a return becuase I have a 12 month warranty on this desk fan. Return is scheduled for the 10th March 2025.on the 10th I get a notification there's a delay so the collection will be rescheduled. No problem new date received 12th March 2025. On the 14th March still no collection of the desk fan. I check my status of my return and boom my return says concluded, what was concluded if I'm still sitting with the item that is broken and no collection took place this happened over 3 times so I had to book a collection of of the broken fan over 3 times already. I have 4 returns scheduled and yet no collection took place to date. I'm so disgusting by the lack of communication and their customer service. It's the 4th of April 2025 and still no item of mine has been collected nor I've I received a call to explain what the issues are. Mine you if I should order and request my things to be delivered to the given address they would deliver so why is it so difficult to get an item collect. All I need is the item collected who do I speak to to get assistance.
