Bought a Challenge Tower fan heater / cooler in Feb for my home office room. Used maybe three or four times in the cold weather than not used. Until last week (only 4 months after purchase) when I used it due to the hot weather. It worked for a couple of days then it stopped oscillating and kept on clicking like it was trying to oscillate. I went over to look at it and the top fell away from the base. I took it back to Argos Worcester Blackpole with my e-receipt and they refused to refund, repair or exchange. They claimed it was not faulty manufacturing and claimed without any evidence that I had broken it myself. It was pointed out to me that the single peice of internal plastic which holds the top to the base was broken and therefore I was responsibe. No amount of discussion would change their mind. I will never buy challenge again and I will avoid Argos in future as their returns policy is open to their own interpretation and gatekeeping and they accept no responsibility for faults and worse - blame the customer for causing the fault. Really shoddy customer service and a breach of consumer regulations.
