Went to Fredy Kia to lease a new car after leasing...

Went to Fredy Kia to lease a new car after leasing before with a different Kia dealership. After negotiations it was agreed upon that I would receive my car for 36 months at 12k miles a year. I signed just to find out that not only was my lease a 48 month, but it was also 10k miles a year. I called to talk to a service manager and was told that if they shortened my lease I would have higher payments as if I was lying about the situation. I ve tried to contact corporate and they have been no help at all. Never leasing at Fredy Kia or with Kia again.
