Energy Comparison company looking to save me money on my energy bill but very pushy, persistent and just wont take no for an answer

They have rung 5 times today, and have been calling for numerous weeks. I don’t answer but that seems to makes them worse.the 5 calls today were one after the other, very frustrating.i called back got a man with an accent (American/canadia ) not sure not good with accents. Got a message with no name of any sort saying to hold and I would be put throught the next available agent! It won’t help but I blocked this number as well - These people are driving me nuts, I’m on crutches and don’t have the energy/time for nuisance calls! This is harassment

Do answer it's a scammer

Scam call from someone claiming to be an Energy Provider. Calling a West Australian phone on a Saturday morning at 6am from the Eastern States is not cool. They've called three times in one hour.
Western Australia does not use Eastern States energy providers and they certainly don't call people at ungodly bloody hours
