Provisions Textbooks and Stationery shocking service

Terrible customer service and late delivery of textbooks for school. They do not answer their phones. Textbooks were ordered on 2 January. Still no books , even though they have confirmed the one textbook has been sitting in their warehouse. The most frustrating thing, however is that one cannot get to speak to any of their employees. 1 star rating is being far too generous! I dealt with a very rude individual named Raeesa... Perhaps a Customer Service course would be beneficial?
