It gets much, much worse
Have a quick search of the MKultra project 68. They took people from Canadian psychiatric wards, drugged them to induce a coma, blocked their eyes and ears, then played a repeating sentence every minute of every day in an attempt to 'cure' them.
One victim was kept in this condition for over 100 days.
Return it. Tell the company you bought it from that the delivery driver threw it at your door and that you tested it, found unacceptable defects, want a replacement and will not accept another delivery that is handled carelessly.
To me, it doesn't matter who delivers what, it could be a foam yoga block for all I care, if I catch them throwing it they're being thrown under the bus for not doing their job properly.
