I bought Accord car with extended warranty from this dealership almost 3 months back, after 5 days I cancelled my warranty (signed a cancellation document) at the dealership. But, it was not submitted for cancellation for more than 2 months and after my repetitive requests on status they submitted after 2 months which resulted in 6% reduction from my warranty refund. I contacted the dealership but they never even bother to respond to me. Please be careful in buying/cancelling warranty from this dealership.
