Pathetic service delivery

Your drivers are the most useless ever encountered. He phoned to confirm the delivery within 15 min, when I called him 45 min later I was told another 5 minutes. I explained I could wait no longer than 10 min. He arrived 15 min later with a very bad, inconsiderate attitude in no rush at all. I shall in future not make any use of your service at all. If you contractors respect me it implies that they have no self respect and is of a life form far below mine. I chose not to deal with those.
