Unhappy client

I logged a complaint to Matrix and requested they provide me with Ombudsman email to escalate my complain and also requested the,proof of renewal of agreement to date I have not receive any of proof of record for renewal of agreement because they renew the contract without my permission . I am so angry because they have sold my account to third party and now that affects my credit score and I cannot be liable for something I did not agree to all I want is to escalate the matter to Ombudsman and proof of record where I agreed to renew
