Female caller said they wanted to invite me to some seminar. I repeatedly asked them who they were but couldn't understand what they said due to their foreign accent. I told them that I am not interested and to take me off their contact database. After hanging up I blocked their number.

I asked several times who was calling me, but due to the callers foreign accent, I couldn't understand what they said. I told them I wasn’t interested and please remove me from their contact database. I then hung up and blocked their number.
