Bad Service!!!!!

We took out a new contract on Saturday, paid the activation fee and later the SIM was not active yet. Sunday morning we phoned them to ask them why the SIM was not activated yet, and the lady said that it will be working in 2 hours. Monday morning, still nothing, I phone them again. Lady says it will be working by 12h00 as they do not work on weekends (Are you kidding me!?).. 13h30 Monday morning we phone AGAIN. AJ says we have to come back to the store as they cannot assist us. This is pathetic! Is this the way you treat your clients?!
