Its a energy company, I have received several calls daily from this number over the last few weeks even though i had not opted in to receive calls, Which is a breach of GDPR. They were unable to tell me how they got my contact details. When i asked him to remove me from their database (which i repeated several times) he continued to try and sell me gas and electric, Even though i told him it was breach of Data Protection until he eventually put the phone down.
Energy company, Couldn't make out the name despite asking twice. Seemed keen to get me to switch providers even though I had only switched last week. Had to pu the phone down as she wouldn't take a polite not interested as a no.
