Account unfairly added

I am struggling to get in touch with the collections team who are the only people that can help. I went through the customer services who were indeed very friendly but cannot help me. I need my matter resolved ASAP. You have incorrectly added me as your customer and blacklisted my name! Can someone who is able to assist me please contact me. I sent an email to *** but to no avail as this seems to be an incorrect emailer address provided to me by the customer services team.
