I bought a hot comb appliance last year first week of April and I had a problem with it this year 17 feb 2026 I reached out on call complaining with it the consultant told me to go to the store to try and get more info if can they exchange it for another one I went there and they told me I can't exchange it because the slip has faded and I don't have they loyalty card of which the day I went there they never had it at all now I can't exchange it
