Since XXXX 2017 their employees were harassing me by calling me 4 to 6 times a day and by following and pursuing me around the city and around my home. The harassments was so unbearable that I conducted some investigations .I found throught XXXX supervisor that the people harassing me where their collection agency ( stellar recovery ) who sent his employees to following me around. They never contacting me by mail but instead they place a device tracker in my car, stolen my driver license and begun harassing over the phone and pursuing me around my home, and my place of work. I have pictues of they employees around my house at my place of work and the device place in my car send them a letter of cease and desist letter by certified mail with return receipt to they address XXXX XXXX XXXX XXXX XXXX XXXX co XXXX they did not responds till now 2 times. later I found that through a reviews this address was a fake address that it do not belong to them. .Under the FDCPA section 805 ( c ) it is my rights to request that stellar cease any contact with me such as waiting for me outside of my home at my place of work or any where else including calling me. because i have the right to remain free from those remedies because they constitute harassment, stalking and etc. this scam clooection agency bought some account from XXXX according to XXXX XXXX XXXX XXXX That they sold they unpaid account to this so collection. I have had issues with XXXX many years ago ( XXXX XXXX ) about their billing. i had a very bad experiences with them till a manager from the billing dept at that time adjust the fees and stupid charges they were charging on those days. before that I called the vice president of XXXX about those issues and he was very nasty over the phone. any way the problem got solve and I paid all m y bills to XXXX. I dont owe any money to XXXX neither to stellar recovery. In my letter I asked them to sent me a copy of any contract or agreement with my signature on it that prove that I have done business with them also to sent me a copy of the contract between them and XXXX which entitle them get any debt from me. They never responds therefore they are not entitle to harass me and collect any debts from me.
