DS got some gaming headphones in Jan from Argos and the microphone stopped working. I returned them as faulty and ordered a different brand in the hope it would last longer. Due to Covid, I couldn't just swap, I had to get a refund then order online and pick them up via click and collect.
I collected the new ones and they don't fit his head very well and are uncomfortable around the ears. I took them back and was told they are consumable electronics and can't be returned. Due to Covid, they have touched his skin so can't be returned as can't be resold.
They are an online purchase, and Argos have a 30 day money back guarantee - no questions asked. Apparently. I'm within my rights to return my online purchase for any reason, aren't I?
