UPGRADING NIGHTMARE

it is a mission upgrading. online they want you to order a simcard, even if you upgrading to your number. so new sim has no relevance. phone in, and you get put on hold 15 times, and then it turns out you have to complete the order NOW for delivery in 3-7 working days. not able to order now for a predetermined date to begin... meaning you have to be available 24/7 for 3-7 days. and if you are not?!! they CANCEL YOUR ORDER. I phoned back twice a week after my first order to only hear it was cancelled, then had to reinstate my order. TWICE. the operator always promised to phone back.... nooooooooooooooooootttttttt.... it is an example of not only poor service but absolutely no competence! i still have not received my upgrade...
