Wrongfully Blacklisted

A Mr price account was opened **********ly using my Identity Document. I Contacted Mr price to let them know what had happened, since they were always calling me about owing them. They ask me to send them my Identity Document, an Affidavit, so they can Investigate. Without any notice, they Blacklisted me, I cant even open an account or buy a house cause of them. The Blacklisting for really uncalled for and Cruel.
