Debt-in the worst to deal with

The most irritating company to deal with seriously. They kept phoning me about debt review I kept telling them I'm not interested but they just kept nagging on and on calling over and over I blocked their numbers now they somehow got a hold of families numbers and started worrying them trying to get a hold of me..the people at this place seriously need to be taught what no means because it seems like they don't understand what no means..
