In XX/XX/XXXX, I contacted Toyota Financial Services when I received an alert that my account was 30 days late from the credit bureaus. I learned that this was reported because half of the payment wasnt received in 30 days. I explained to them that it is my daughters car that I co-signed for and her father and I split the payment. I asked what I needed to do. They later told me how much I needed to pay and I paid it with my debit card over the phone. I started to receive call from TFS about the account. I then learned that everything we paid the {$10.00} fee if we paid after 10 days they never credited the money to the account for the fees. They kept putting it toward the principal. This was the second time this occurred. I asked them why they would do that and there was no way for me to specially direct my money when I pay because they do not give the option. They then corrected my account. Again, this was then second time. Again later, I began to receive phone calls about a missing payment of over 200 and received another 30 day alert in XX/XX/XXXX. I asked them to research my account because of all the issues I had been having. They claimed they would and would get back to me. Different people would continue to call me daily and I would have to explain over and over while each person claimed they would research. However, we continued to make our payment. Now we are in XX/XX/XXXX. I received these notices that our account was becoming more delinquent but it was not accurate. I was then informed that they never put the money I paid over the phone or Im XX/XX/XXXX toward the past due of XX/XX/XXXX. I asked why they would do that because it impacted my credit score greatly. The representative said that people post payments different and that you have to call in to specify. Again, o told them that this was a flaw in their system and that it should give the option of where my money is going when I pay online. There is only one box. Nothing for late fee and nothing for overdue balance. I asked to speak to someone else that could help me get my account back on track. I was transferred to another representative who told me that he could not tell me the parameters for an extension because then you would just say what you need to say to get it approved. I was appalled and asked to speak with a manager. The manager apologized and told me that she was going to do an administrative extension request to bring my XX/XX/XXXX and XX/XX/XXXX accounts to current and on time. She told me that it could take and few days to see if it was approved and to call Back. It was a Friday so I waited. When I called back a few times there was nothing. A different representative told me that there was no such request in the system. I began to cry from the stress and my daughter had just had XXXX. The representative them told me that the XXXX was a qualifier and she approved my exrension right on the spot. She told me that it could take 1-2 weeks for the paperwork to come in the mail to sign. It never came but it was approved. I kept calling. TFS finally sent the paperwork for me to sign electronically in XX/XX/XXXX. I signed it and continued to make my payments throughout. I noticed a few weeks ago that my account stays was still never fixed for XX/XX/XXXX and XX/XX/XXXX Im my credit report. They told me that I had to dispute it with the credit bureaus. I did this. They have since codes XX/XX/XXXX and XX/XX/XXXX as no data when they where in good status and left XX/XX/XXXX and XX/XX/XXXX as delinquent. I am very distraught over TFS and there fraudulent dealings and refusal to do the right thing. I need my XX/XX/XXXX and XX/XX/XXXX put back to the on time payment. I need them to accurately reflect XX/XX/XXXX and XX/XX/XXXX as current since they approved the extension to put those months to the back of my loan. At the least, they should have coded those months as no data. Not all of the months that were paid on time. XX/XX/XXXX is the only month that should reflect 30 days late and that is becaus only half of the payment was late.
