Worst customer service ever

Worst customer service ever! Went to the toilet, the driver called (didn’t bother coming to the flat as the supervisor would have buzzed me) and left. Now will only come back tomorrow. That after I saw the missed call and tried to call the driver back over 30 times! Moral is the story? Don’t go use the bathroom if Ram delivers. They’ll not bother to come to the flat. They’ll leave and come back the next day. Will never use them EVER!! TakeALot uses Mr Delivery. Maybe Rain should use them too.
