Misleading Service

I upgraded my contract via the sales department and the phone was couriered to me. It states on the form given that the sim will be activated within 48 hours. I called yesterday when the 48 hours were up and said the sim is still not active, was then told no it’s 72 hours. Which is highly misleading due to the form given clearly states 48 hours. Nevertheless I waited until today which is 72 hours and the sim is still not active. I called again and was then told 72 working hours!! This is pathetic service no where does it state working hours. This is seriously lousy service
