We had a service rep come to our door today. My husband told him we were not interested at this time and the rep got belligerent with my husband. The conversation went as follows:
My husband: "We are not interested in solar at this time. Signing a 20 year contract to pay for it isn't appealing" and
Rep response was, "That's fine, not everyone wants to be a millionaire."
My husband called him out on the snide remark and the rep called my husband a few names. Not respectful or professional.
