Why deliverers are always alone in making deliveries even when the total weight is downright abused. I live on the third floor without elevator and I ordered for about 100kg of shopping and the delivery man was the only one to mount them! This gives a very bad image of your company which visibly cares only about profit and absolutely not the health of its employees. Your deliverers are nice, punctual and professional but, given your company's policy, I will not order from you in the future.
