Poor customer service

I have been trying to call Matrix for the past 2 months and all the consultants are not picking up my calls. I have wasted a lot of money trying to call the customer service and contracts department. I have sent numerous emails to attempt to get assistance or call back, but no one bothers to contact me. I have also sent an email to complaints on their website but no one is still handling this matter. I have 2 contracts which I need to downgrade because they are expensive for me now and no one is willing to assist and this is because they just want to continue debiting my account every month for their benefit.
