ERC Debt Collection Complaint

ERC Debt collection department,

Other (i.e. phone, health club, etc.) Cont'd attempts collect debt not owed Debt is not mine Pennsylvania

I had contacted the debt collector on numerous occations and direct disputed it stating that a debt for - was not mine. They were very rude the first 3 times. The last time I contacted them I had - on a recorded line so they could verify that I was not the person they were trying to collect the debt on. I had asked them to get this debt off my credit report because it is not mine and it still is showing up and I am very upset that my credit score is hurting because of debt that is not mine. I want to know why it even showed up on mine. Do they not check SSN or Birth dates. Me and the other girl have similar names but not same birth dates. I am very upset and I would like an apology for the way I was treated by the company. I told them that and I got no response.
