Cox Communications review: Payment - collections issues

COX Communications and Waypoint Resource Group
I am upset because my name was associated with a collection's agency.
My name was the only item that was correct with the collections agency invoice.
The collection agency sent a letter to 97 Anchorage Dr, Newport news a [protected]. This is not my address
The date on the invoice was August 13, 2019
Fortunately, I knew the person receiving the bill at his home in Newport News. He handed me the Waypoint collections letter early October. The date on letter was August
A few facts that are upsetting
• I do not live in Newport News nor is my address on Anchorage Drive
• I have never paid a bill on this COX account.
• I called COX to find out what was going on and why I had not been previously informed of this bill.
a. They did not have my address correct.
a. The had a different e-mail for this account.
b. The password for the account was not mine
c. The secret password was not mine.
d. With all this wrong, except for my name they could not give me any information on the account.
I asked COX to send me an itemized bill. The letter was again a letter from Waypoint collections agency with the amount due. The only reason I receive the letter was I gave them my correct address.
I called COX back and told them I wanted an itemized bill if they expected to me to pay them. They told me since the address was wrong on file, the password was wrong, and I couldn't answer the secret question. I could not get any information about the bill. They did say they were sorry.
In the meantime, my Credit Report was severely adversely affected.
In order to keep my Credit Report being further affected, I paid the $632.49. The original COX bill was $420.79. My intent was to stop the Credit Report issue and argue the outcome later.
Help me fix a few glaring issues.
Make sure the account is closed. The account # listed on the Waypoint Bill was 4963285. The account was address 111 Browns Lane Yorktown Va
I don't feel that I should pay the extra money for collections agency costs. The original settlement amount was $420.79, the final was $632.49. Note: eventually got the legitimate payee to give me the money owed.
$632.49 -$420.79 = $211.70
My Credit report should be restored to eliminate the bad credit reported.
Thank you for your help and assistance.
