Caller: "Capital" Investments/Services/Finance (can't recall)

Overseas call centre that takes a while to connect when you pick up.
They have called my deceased mother's mobile number. I asked to have the number removed from their list they aggressively talk over the top of you. I advised the owner of the number is deceased & he started trying to sell to me. I remember when calls like this would just hang up...now they argue with you.
