Pathetic service and dont deliver paid orders

Clicks online takes your money, doesnt deliver the good paid for and then subsequently ignores you. What a horrible experience ordering from clicks online, you pay a service fee to get your oder delivered within 1-3 business days then after a week of queries why the order still says you pending they ignore you, call center agents cant help either. Their Facebook representative says they will escalate and nothing happens. Have sent so many unanswered emails. How can big companies in todays economic climate take peoples hard earned money then not respond and not deliver either.
