Grossman Nissan

This dealership is the WORST. We purchased a vehicle from them in May 2015 and were promised a replacement window visor at the time of purchase. Told for MONTHS that it was on order and that we'd be reimbursed for our inconvenience with gas cards and oil changes. Finally spoke with someone about 3 weeks ago and were then told the part was NEVER ordered but they'd place the order now and to expect a call back. No phone call, still no free oil changes or gas cards. I've left voicemails/spoken with various contacts 1-2 dozen times with no resolution and continuous lies that our concerns will be addressed. On my last attempt to resolve this told the Business Manager (via voicemail) they had 2 days to find ANY solution or I'd contact the Better Business Bureau. This was about 2 weeks ago and I'm contacting the BBB today. Wouldn't recommend Grossman Nissan to my worst enemy.
