Bad Communication

As of 6 June 2015 Jet Stores has been adding costs to my account for a service called Mobile Content Fee that i never asked for or subscribed to. I have on many occasions via email as well as telephonically requested information as to why i am being charged for this service and did not once receive a response from any of the staff members of Jet Stores. on 14 December 2015 i sent a email to Chantelle Usher the Collections Manager and have since not received any response to my email. in the second week of January 2016 i received a call from one of the consultants of Jet Financial services regarding my outstanding account that is now overdue and after requesting that they reverse all fees that was charged on my account before i make a payment the consultant threatened me with my account being sent to the Credit Bureau instead of trying to solve my query and fixing the issue. i have asked one of the Consultants to contact me with regards to my query and i still haven't received any response instead all i'm receiving are text messages and emails about my account being in arrears. This is really bad customer service and i would like for you to look into this matter. Thank You
