Business ProfileforMarc's

I went to Marc's to return a phone charging cord & car plug-in that I purchased 2 or 3 days before. I had the packaging and receipt. The guy at customer service said he needed to scan my driver's license to return a $6.99 charger. That seemed pretty intrusive - it's not like I'm returning an expensive TV or wanting to buy alcohol or cold medicine. I asked to speak to the manager. I asked the manager why is this information needed - his answer, "I don't know.". I asked will I start getting junk mail - his answer, "I don't know." I asked if I would start getting junk email - his answer, "I don't know." I asked what does Marc's do with my information - his answer, "I don't know." But he did say that scanning my driver's license was the only way I would get my money back. Not only did he not know anything, but he didn't care either. I opted not to return the item that I won't be using (because it's defective) because I feel like Marc's is taking personal information and doing who knows what with it, but if I want my money back I don't have any choice but to give it. I'm really angry about this. I'm angry that Marc's wants this information for who knows what and that returning an item is so intrusive. It's not like Marc's is a high end jewelry store or a pharmacy. I'm also angry that the manager couldn't answer any of my questions and that he was completely indifferent to my concerns. I tried to email the corporate office and after providing all my information on Marc's website it requires you enter a security code. How do I find the security code? I have no idea as the website provides zero clues. So contacting them through their website isn't possible. When I used the charging cord I purchased my phone would tell me the port has moisture in it, which does not happen with any other charging cord I've used. So I'm stuck with a defective cord/charger.
