FALSE CLAIMS and nowhere to pay!

After many attempts via in store, on calls to customer service and with a virtual assistant- I am still left with nowhere to settle my dispute. 
I signed up for WiFi in May then was pressured for the free mobile (By way of a new phone) even though I had a compatible iPhone) which the customer rep could not get to work.

I was told it was a 240 phone but it was not. It was a 418 phone.
This was not the worst of it.
After getting the phone, it didn’t work. The texts went to my old IPhone and then after 2 weeks- the email failed and I had zero calls coming to the new phone.
I had to purchase another phone with a different provider in order to have a working line and to receive my texts. 
All this time I was stopping by and calling to get the phone issue solved since my old number was crucial to my business. 
It was such a mess I canceled the WiFi and as soon as that happened? 
I was locked out of my mobile account. 
I had no way to access my old number or my phone bill. 
It gets worse. 
I called the company and then 2 hours into the call I was told I was going to be able to return the phone that never worked. 
This was a false. 
Instead of the shipping label being sent to me? I was being billed over and over for the same phone. 
The shipping label was not sent to my email but a final bill was. 

Tired and done with the time I wasted- I went to the store to lay the final bill. 
The manager and the VA could NOT ACCEPT my cc payment for the phone 

Now I am here. 
complaining to the forum for the last time. 
Why is there no way to pay for this terrible service so my credit is not hit?! 
You all lied to me over and over and so besides the fact that this company will never get my business again- I want it to be over so I can move on with my life. 
Where can I get this completed? Why make it so difficult to pay a bill?!
