I missed a call from this number and when I called the number back, an incredibly rude person answered and said her name was Kim. She said, "You need to check your voicemail to find out who called you." I advised her that they didn't leave a voicemail for me check. I asked to speak to a manager and she said she's the only one there. I told her I needed her managers name and number and she said, "You're not getting it from me." and she hung up in my face. HORRIBLE customer service. I would NEVER use this company for any reason.
