Calls Ended by Advisors - Corrale Issue

Hello. I have Corrale straighteners which are no longer holding charge. I called tonight and was told they were out of warranty and a repair would be £100. I explained that a 2 year warranty was poor on such an expensive product, and the person I spoke to said if I could find proof of purchase it would be repaired or replaced free of charge. I asked him to wait while I located it, but he ended the call. I called back again and spoke to someone else - and explained issue, and what the other person said. He did a video call to see the straighteners switch on (???), then said my only option was a discount. I explained again what the first man had told me, and he wanted to see proof of purchase and connected to another video call. I could not understand how to show him my email on a video call and asked him to explain. He said he would, but then ended the call. Please understand I was entirely polite throughout. Is there any way of contacting them other than this? I really don’t appreciate being told two different things then being disconnected twice.
