RUDE AND *********** STAFF FOR A BIG FINANCE HOUSE

I contacted the the service provider and was able to speak to a gentleman named Zubair who was rude and impatient. after a long call of him providing misinformation on my query. After that he started to scream at me and when he was done he put the phone on hold pretended to transfer the call to manager which he came back after a while to say the manager is not in and i asked for another manager or the CEO he then again screamed at me and and dropped the phone on my ear. I request an apology from him, the company to provide me his latest customer service course he attended and its outcome. in terms of Treating customers fairly this gentleman have been unjust to myself.
