Received a call from Integrated Services at XXXX. I can not recall the mans name but, I was told I owe this debt for a payday loan back in 2014. I said okay, send me proof the debt is valid and I will work on paying it. he said why do I need paperwork? and proceeded to call me a XXXX and then hung up. I have also received calls from them at my work number as well. Please stop these scammers!
