I was contacted at XXXX CST by a XXXX XXXX . She asked about an outstanding invoice with XXXX XXXX. She asked if I was having financial difficulty, I told her no, that my contract ended. I was obligated to pay 6 months, I paid that. She asked if I read the terms and conditions of my contract, I explained that I had. I told her I had a copy of my contract I would send her that states the effective end date and a highlighted portion that shows the automatic rollover clause was NOT effective per my request. XXXX said I had to pay immediately, I told her I was not paying something I did not agree to pay, when I hung up the phone, she immediately called back, I sent the call to VM. XXXX then called back immediately a XXXX time.I sent that to voicemail. She the called my employer, asked for " Who ever was over me '' and then complained that I was rude.
