Sunglass Hut complaint: Poor Customer Service

I drove a long way to get to this Sunglass Hut store. I pulled up around 3:20 pm to a store that’s scheduled to be opened until 6 PM. Walk over, pull the door, it’s locked. I stood around for a little while in the heat to see if someone shows up as there was no note on the door. Walked in to the store next door to ask if they know why the place may be closed and they told me that this isn’t anything new, that they close the store at random hours and simply leave. Since I have a return I called the store later in a week to see if the online info is wrong and make sure that they will be in the following evening so I can return my purchase. The person I spoke with named Mike, that would not release his last name claimed to be a manager. I told him the situation and my concern that this will happen again and I’d like him to assure me that someone will be in the store the following evening. Mike from the beginning of the conversation was unapologetic, rude, kept talking over me and saying things like, I’m not assuring you of anything and I live in Delaware and I will not come in here on my day off to babysit these guys . I asked to speak with someone else to what Mike said there is no one else and if I don’t like the way I’m spoken to I need to take my business elsewhere and Sunglass Hut will not mind if I take my business elsewhere either. He proceeded to sarcastically wish me to have an excellent day and hung up on me. I’ve been shopping at Sunglass Hut for years because they carry my fav brand, Maui Jim, but I will never take my business to SH again.
