Wells Fargo trying to collect on a mortgage. I said, "I don't have a mortgage with you". They became verbally abusive and insisted I did and was 7 months behind. I politely asked them to verify whom the number they were trying to call. They stated my number. I asked them politely to verify the name they were trying to reach. Not my name. They asked me to verify my address. I refused. They said I owe them money. I asked to speak with a supervisor. They hung up.
