Next Business Day On Site Warranty - MY FOOT

I had two calls logged with Dell for two Optiplex 3020 computers. Both machines came with \Next Business Day On-Site"warranties.<br> <br> Call no.1: Logged 6 January 2015. Eventually closed Sunday 8 February 2015 - more than a month later. Technician from partner company was only informed of this call the week before.<br> Call no. 2: Logged 26 January 2015 for a DOA. Still not fixed. Call Centre keeps passing the buck."""
