I got a call and the female stayed silent for 10 seconds and I wasn’t talking too until she said hello then hung up, I keep getting calls from this number with the last 2 digits changing every time I block

Caller: they refused to say

they asked for "name thats not me" without saying who they are, said my number was in there database under "name thats not me", i asked them to remove it and they refused but told me to look into it but would not give me a company name to look into it, was then very unprofessional as they stayed on the line and argued instead of hanging up
