Telling a client they are stupid!!!

My husband went yesterday to simply ask Cash Crusader Brits Branch to help him start the laptop he purchased 24 January 2015 on the slip says 6 month warranty, he never screamed warranty he simply asked the sales person to please help him to just start up the laptop as the hard drive had crashed.<br> Today he phoned the store to speak to the franchise owner he was rudely told that he can call headoffice, my husband called head office to a lady who was really friendly and she said the matter will be seen to.<br> Later he received a phone call from head office from Lodewyk who promptly told him th warranty had been voided because we took the laptop to a laptop specialist, the desired reaction would be for Lodewyk to have said give me the report and I will deal with the branch instead he arrogantly said to my husband they will put the footage up of him losing temper and that will weaken his case and that there will be no apology from the sales person who called him stupid. it was a he said she said story and no proof. This is disgusting service to say the least as I heard the telephonic conversation myself. They cheat people out of their money and have no people skills. TERRIBLE!!!
