incompetent customer service

My husband bought me a new motorola tracfone. I called the tracfone phone # on my activation card on Friday, 10/30 I told the customer service rep that I wanted to keep the same phone number and that I had a new phone I wanted to activate, well it finally started working on Sat. 10/31 but with a different phone #. On Monday 11/2 I called the home office # in Florida and they said they would overnight a new sim card to me. I never received it, I called them again on Wednesday they again told me they would send me a new sim card overnight, I never received it, my husband called them Friday 11/6 they told him they would overnight a new sim card and gave him a fed ex tracking #. Well guess what it is Saturday 11/7 and I still have not received my overnight sim card, and I checked the tracking # on fed ex and I will not receive it until Monday, 11/9. This phone was a birthday present which has turned into a nightmare.
