Wrong phone

I app**** for a upgrade on my cell phone contract around 12th of March 2021. After two weeks I made followup and they said they waiting for stock. Then after another week I called they told me that A31 is discontinued so they have A32 but they still waiting for the stock and said they will receive stock the following week. Yesterday the 23rd of April 2021 I received a phone only find the A31 that they said they don't have it anymore. What should I do with this A31 since I waited forever for a wrong phone.
