Buffalo’s bad service

I was notified that my delivery would be delivered on the 1st of June. Wasn’t delivered for reasons - not at home/insufficient address but I have always used this address with Buffalo & I was at home ? Nobody called me to even ask about the “insufficient address”. My order got rescheduled to the 3rd & nothing came. I keep on getting automated messages from the company saying the delivery is being dispatched but still nothing. I have exhausted all my options now I just want my money’s worth.
