Asked for a person unknown to me, Then said it wasn’t a person specific call and went on to say just wanted to ask 4 household questions. I said I wasn’t interested then hung up.
Caller with Indian/Asian accent asked me to confirm number. I said as he has called he obviously knows it. He then asked me to confirm my address. When I asked why he said all he needs is a simple yes or no answer. I asked why he called, He repeated the yes or no bit. I hung up.
