Product: Debt collection

Credence Resource Management LLC To Whom It May Concern : I am disputing a debt from XXXX XXXX and am requesting your assistance in clearing this debt since I have been unsuccessful at this point. 
XX/XX/XXXX : XXXX XXXX  installed cable service at my home at XXXX XXXX XXXXXXXX XXXX, XXXX, CA XXXX. 
Prior to the installation, I received calls from XXXX XXXX telemarketers. Id just moved back into my home approximately three to four weeks before the installation. The Telemarketer I spoke with offered me promotions and cable services which came to {$110.00} a month. The Telemarketer said I had a 30-day trial period. 
Shortly after the installation, XXXX XXXX started sending me bills for {$210.00}. I called XXXX XXXX a few times and they would not help me. 
After approximately two weeks, I received a bill from XXXX XXXX XXXX for my cell phone with an approximant {$20.00} increase. I called XXXX XXXX XXXX, and they said when I received XXXX XXXX  services my cell service increased. My XXXX XXXX XXXX cell service was a business rate Ive had for several years. Ive been with XXXX XXXX XXXX for over 20 years. I told XXXX XXXX XXXX that XXXX XXXX never told me my cell phone service would go up each month for installing XXXX XXXX. XXXX XXXX XXXX immediately changed my cell phone service back to my old plan. 
At that time, I called XXXX XXXX again and told them that my XXXX XXXX XXXX cell service increased. XXXX XXXX told me there was nothing they could do and I owe XXXX XXXX {$210.00} dollars. In addition, I told XXXX XXXX that the Telemarketer offered me promotions that I never received. XXXX XXXX said they did not know about the promotions. XXXX XXXX lied several times throughout the whole process. I told XXXX XXXX if they can not help me I would have to cancel their services. 
XX/XX/XXXX : ( fifteen days after installation ) I cancelled XXXX XXXX and returned all of XXXX XXXX equipment. XXXX XXXX  started sending me bills for {$600.00}. I called XXXX XXXX several times and told them what happened and asked why am I getting charged {$600.00}. XXXX XXXX said the charge was for an early cancellation fee. I told XXXX XXXX the Telemarketer said I had a 30-day trial period and if I cancelled within 30 days there would be no charge. 
After two or three months after cancelling XXXX XXXX, Credence, the Collection company started calling me daily. I told Credence about the lies and unethical ways of XXXX XXXX and Credence did not care and continued to call me. 
On XX/XX/XXXX, I sent a letter to XXXX XXXX and Credence regarding this dispute. 
On XX/XX/XXXX, Credence sent me a new billing statement and lowered the charges from {$600.00} to {$140.00} with Reference ID # XXXX. I called Credence and told them again why I think it wrong that Im being charged these fees and Credence did not care. 
On XX/XX/XXXX, Credence sent me a second bill for {$140.00} with Reference ID # XXXX. In the mean time, I called XXXX XXXX and they said all charges had been removed. In addition, XXXX XXXX had me talk to the manager of the Collections Department. The manager said the XXXX fees were from XXXX XXXX and the fee was carried over when I cancelled services. The manager said after listening to my dispute that he thought the Telemarketer and XXXX XXXX were wrong. The manager said he put notes in the file stating he recommend to drop the dispute and to wave all fees. I called Credence and told them that XXXX XXXX manager said Credence can call him and would recommend waving all fees. Credence said they would not wave the fees. 

I have also sent a letter to the Federal Communication Commissioner ( FCC ). I would really appreciate your assistance with this issue in clearing this debt. Please contact me at your convenience.
