FIDELITY ADT: HAPHAZARD BLACKLISTING

Fidelity has blacklisted me with all credit bureaus. The office staff viz. the credit control dept just don't care/ or they don't understand the implication of ********** blacklisting . I have been in contact with them since January 2019 requesting them to remove my name as their client ever since I learnt that I was blacklisted (I AM NOT EVEN THEIR CUSTOMER /CLIENT) I am an employee at an institution where ADT uses the premises and provides a service in lieu of payment. My advice to anyone using their services "check with the credit bureau" whether they have done the same with your account. The office staff need to be trained perhaps???
