How to sort out orange sim card?

On Saturday I moved onto a sim only plan on orange. They said I could keep my number but gave me a new number, and i would have 200 minutes and unlimited texts added in 24 hours-therefore the sim card had a temporary number that after 24 hours would change to my old number and add the minutes and texts. However, 48 hours later this hasn't happened so I have reverted back to the original sim card so I am able to be in contact with people. Also on the new sim, I call 150 to see how many minutes there are and it says I have 26 minutes and no texts in my bundle???????? WHAT???
