UPGRADE DONE FRIDAY - STILL OFF LINE MONDAY!!!

So much for being excited over a new phone - I received my new upgrade phone on Friday - a sim swop had to be done as it uses a smaller sim card. It is now Monday and still no service - I phoned *** since Friday evening - went into the shop on Saturday as *** told me that is the only way to get the sim swop activated. I was told that it would probably not happen over a weekend and that there was a glitch in the sim swop process - so wait for Monday as they did send a request on Saturday. This morning I phoned *** only to be told to phone 1761 - I asked if I should add 083 in front and I was told \yes"!!!!! This does NOT work!!! Back to ***8 then I'm told \""nooo 1761 will only work on a cell phone - I lost it - how do I phone form the very cell that has NO service??? Then I was told to phone *** - there you have to put your ID no. and sim no. all automated and guess what - sorry the service is not available at the moment!!! I would really really appreciate it if I can get my phone to work!?!"""
