24h turns 7 days and query still not resolved

A few weeks ago my contract phone was ****** after just recently getting a new phone I went to a store and bought a unrica'd Sim so that I could get a Sim swap. a Day later I phoned the call center to process the Sim swap. I Gave all the information needed to do the sim swap and the person gave me a reference number and said they'll contact me the next day . The next day no one called me back so I decided to Call the Call Center again and gave the person my reference number but after giving my information AGAIN they told me that I had already rica'd the Sim card and must get a new one. I bought a new sim but have been struggling to get my Sim swap. Every time i call its the same thing over again and again. Every time they say \we'll call you back tomorrow "no one calls back and if they call back they start proces over.I Think that after a week of spending my airtime and giving out my personal information that I will not be upgrading my contract next month and will be taking my business elsewhere.
