GMAC THEY ARE CROOKS!!!!!

I currently have a leased vehicle from GMAC... Big mistake.... I send in my payment on time for the loan, it will take them almost a month sometimes to credit the account. I am stuck with the late charges on it and it makes my credit report look really bad. The latest stunt by them was that they had said i was late on my payment so I went ahead and sent the money by Western Union to make sure it got there as quick as possible. I went ahead and called them to verify they had the payment in and the gentlemen I spoke to was really snotty and he told me that ok he had gotten it and ok this takes care of November and wheres December's at. I check my books on this and I should be atleast one month ahead and so I told him how would you like to talk my lawyer and instantly he said ok here it is you are fine now and current. I will tell everyone one thing stay away from them.... They are crooks!!!!!
