Absolute disgrace of a company

WAS a customer for 8+ years until today. My family and I had fallen on some hard times recently. I set up, and was eligible for, monthly installments on my past due amount. Paid the $50 set up fee, received my confirmation, and I thought that was it. I was good. Come the 27th, they decided it would be a great idea to turn off my service WITH an installment plan active that I paid to set up. When I call, several times just to get someone I can actually understand, I’m told that there’s absolutely no record of me setting up the installment arrangement, though, again, I have confirmation of it being set up, and that my services would not be restored until I paid the entire amount past due, TODAY, that I set up the installment plan on for 12 months. To add the cherry on top, when I spoke with a “supervisor” she became VERY rude and a complete smart [Edited: "Profanity"] when I advised her that I was in possession of the confirmation of the plan being set up. So over this company. [Edited: "Profanity"]. Now, they won’t be receiving another dime from me.
