re: TELECOM DIRECTORY

After we made payment to Telecom Directory in Nov 2017 and at the same time sent a letter to cancel our subscription with them, they keep getting collection Companies to phone me saying we owe them money and everytime i send emails to these Companies showing them the correspondence they just ignore me. I can never get hold of Telecom Directory and they also ignore my emails. I have read so many reviews on them and seems like they are ******** Companies. i have had calls from NCR Legal, Debt Review Collections, Rollins Inc and ITC Summons, i have tried phoning some of these places, but always goes to voice mail. I am really tired of all the harrasment now, how can we stop this.
