DARCARS Toyota of Silver Spring

This has been the WORST car buying experience I've ever had. I already had the car picked out online and contacted sales 100% ready to buy. It took several days for a sales rep to even respond to me after I reached out several times. Then, I only got literally one-sentence email response a day. Moving the process along felt like I was having to beg them to let me buy the car. This process has now dragged out into SIXTEEN DAYS for and they still haven't finalized the purchase ***AFTER already debiting my account for the downpayment!*** Every time I call in, Larry N. in finance is "out of the office", they take DAYS to reply to my emails, if they even respond. I call in asking to speak to ANYONE else and I get stuck on hold for 20+ minutes until I give up. I have emailed the head of used car sales, I spoke with the head of new car sales, I emailed the head of finance, and NO one has helped me or gotten back to me. As of today? I have given them the signed papers, a $2000 downpayment, and here I am 16 days later STILL WITH NO CAR. I'm about to initiate a chargeback to get my downpayment back and buy elsewhere. I literally have a delivery company ready to pick up the car and bring it to me and I cant give them a pickup date because NO ONE THERE IS RESPONDING TO ME!!!
