Thanks for your post and welcome to the Community Forums, lynnep1964,
Sorry to hear this had occurred.When did you make the change and did you receive a copy of your new package details or contract? Changes are not immediate and would usually take place on the next bill cycle. Did you miss any payments? You can find detailed billing and payment history through your online account here.
If you do need any more help let us know.
Cheers,
Corey C
