On XX/XX/19 I turned in a lease XXXX ( GM ) and due to GMC loyalty was informed that GM will handle all origination fees/payments remaining. 110 days later I received a phone call from GM demanding {$800.00} dollars for lease return. I immediately called the dealer XXXX XXXXXXXX XXXX  XXXX/and we had a conference call. General Motors apologized and sent an email to me apologizing for the error and claimed all origination fees and wear and tear was taken care of and balance was XXXX. The Robo calls continued from GM and no real person continually. I would call GM and they claimed I still owed XXXX plus. Mind you I never received an invoice from GM. Yet they claimed they mailed an invoice. Again I was informed that my credit hit would be corrected and apologized for the error. To date I have I still have a negative hit on my credit score that I worked 40 years to keep a perfect score. I was informed by General Motors that negative hit will be removed and that they will make contact with the credit reporting bureau! Yet Im informed by XXXX  that the negative remark will remain even though I provided an email from GM apologizing and writing to inform me that they will be in touch with the credit bureau to remove the negative remark. Dealing with General Motors has been my worst nightmare. Every advisor I spoke with had a different story and informed me that my Acct was settled. Yet the robo calls continued by GM and couldnt talk to anyone! Had to call each time hearing a different story and told that my case went to a different division. I still ended up having to pay {$540.00} plus which I was informed in the very beginning that these charges would be waived and my credit hit would be repaired. I had a perfect rating and GM ruined all of it. Ruined my perfect credit score. I have a new vehicle XXXX XXXX. Had I known that this unbelievable lies would occur and continual harrsement with Robo calls and different story each time by GM reps, I would never have purchased a other GM automobile. Once this existing lease is up my family and friends will never buy or lease a GM vehicle again. Promises made that Im a loyal customer and all fees waived including 2 remaining payments. So we went with another lease and traded in the existing car. 110 days later I get a phone call demanding {$800.00} dollars by GM and never knew that there was an issue. They claimed they sent invoice. Ive always paid every creditor on time for perfect credit score! GM ruined my perfect credit score and not fixing it as they promised. Never again will I purchase s other GM vehicle. The internet is full of complaints with lease end issues. The Robo calms are a joke. Its a recording and continual. Yet every agent I talked to had a different story on my Acct. I still ended up having to pay {$540.00} & I dont even know why. I was Informed by the GM agent that all this will be corrected after my dealership did a 3 way conference. Yet nothing was corrected. I hate my new vehicle due to GM ruining my perfect credit score that I worked so hard to get. And never realized there was an issue being informed that all fees are waived when I traded in my lease to get into a new lease offered. Robo calls with a recording are stressful and conversations by agents that claimed all will be taken care of and not to worry. Yet they went from XXXX demanding payment - then dealer told GM agent to correct and informed all is good. Yet Robo calls continued and I would have to call them. They would demand payment this time {$540.00} when I was informed all fees waived and GM apologized for the confusion. Such lies. I will never buy from GM again. The complaints on line about lease returns into the thousands. This kind of abuse and lies by GM needs to stop.
