Who called from 2037641369

Called three times today, I answered with "Hello" all three times...no one on the line....just dead silence.

Second call from this number. I just blocked the number.

2 calls within 2 hours today. no one there.

Same here...called twice today with no answer. We called it back but no one answered

Finally! They called again. We answered. Someone was there. Apparently, it's a solicitor trying to get you to switch your electric provider.
