Complaint Review: Safe Home Security Inc

I have been with Safe Home Security for over 4 years now. I initially signed a 3 year contract in which my term expired over a year ago. Last year, Safe Home had called me repeatedly to ask if I would like to renew my contact and I stated that I would not like to renew. Different representatives would call me every day and I strictly told them I do not want another contract. On May 5 2017, I called to cancel service that I would be all set. I saw my credit card get charged after and I called back to figure out what is going on. They told me I need to email a written confirmation letter for cancellation and I did that on 6/8/17. I called on 6/21 to follow up and now they are telling me that I am under contract until January of 2018.
