Bad manners

I phoned this business this morning to enquire about parts. The phone was answered by a man with the words "Grahams Appliances. . "bas well as his surname.I then requested to be transferred to the spares department. The answered me saying "Can I help you?" and I repeated my request to be put through to the spares department. He then answered me in a vey irate tone "Can I help you?" No mention of the fact that I could be speaking to the soares department or if he didn't hear my request. Just this irritated voice. When I saud to him that I'd rather not do business with somebody treating me in such way, the phone was put down in my ear.
