Not Enought Store Credit, told to call Experian???

I went in to get an early upgrade and was told I didn’t have enough store credit, they told me to call Xfinity mobile support, so I did. They told me to call Experian to get a credit increase. What the literal heck is that going to do?? This is my conversation. Can someone please explain how doing this will increase my credit??

Me:I saw that I was eligible for an early upgrade. I went to the Xfinity store to get a new iPhone 15 pro max and they said I didn't have enough store credit. They said I've been a customer a long time that they didn't understand why. They succeeded I get in contact with mobile support to see about a credit line increase

Xfinity:As I can see that you have $0 credit score and you are also eligible for 3 lines and you have taken that 3 lines also 

As you mention that you want to upgrade your device so let me help you with thye credit department number 
So please be rest assured the moment its increased you can upgrade your device into 15 pro
Just call on that number and they will increase your credit limit and lines in your acccount

Here is your credit department number Equifax    800-685-1111Experian   888-397-3742

Apart from this, is there anything else I can assist you with?

Me:What's the number for Xfinity credit department, what will Equifax do for me? 

Xfinity:They have the access to increase your credit limit in your Xfinity account 

Me:I called and there was only two options, get a credit report or freeze my credit 

xfinity:Ok then just called on the other number 

Experian 888-397-3742

Me:Still two options, none of which is getting any kind of credit increase. Check on a credit freeze or get a credit report are the only two options 

Xfinity:Noted that just note that 2 number 

Me:Option 2 is getting credit report, how is getting my
Credit report going to help me increase my credit limit

Xfinity:As I just asked my supervisor they said that just click onm the credit report

Choose the option credit report 

Me: ok then what?

xfinity:And after 24 hrs they will update your account 

and increase the limit in your Xfinity account 

Does this make any sense at all to anyone??? After today I’m ready to pay off my phone and go to another carrier
