The Riverhead, NY store service staff were indignant and disrespectful. We specifically purchased a PC from them for their service offerings. When my mother went in for a class, she was told basically they only teach how to turn on and off the PC. We were told the classes would help with the additional software, and learning Windows 10. We had asked multiple and specific questions when we initially purchased the additional Total Tech Support. But afterwards, there were all these additional costs. We had asked about installment, than they were going to charge an additional $100.00 to attach to the printer and install the purchased software. Quite frankly I would not reccommend Best Buy, I am thoroughly disappointed and I am awaiting a response frm the Manager. The service and the knowledge of the employees is appalling! If I could I would give a negative 10 rating. My mother asked for the supervisor "well he is gone now for a half hour". Ok, well who else can she speak to ? Needed to be the response, or how can I help. This is really simple.
