Customer service complaint

I set up a payment arrangement with two different people within a two day span and both told me that it was OK to pay the full balance due on my account by October 12 and promised me and swore up and down that my services would not be interrupted I got up this morning and my services have been interrupted. I am so mad because they never once said that the Xfinity plan would take over if I didn’t pay before then Ann swore that it would not be interrupted at all so now I had to find a payment to make for my TV to come back on this morning  Someone needs to refund me my money back or apply a big credit to my account to bring my account current since I was lied to to two different people one on the chat by an agent and one over the phone by a customer service rep. I have been with this company since 2012 and I cannot believe that I was treated like this  And that no one knows that ends and out of what is allowed and what’s not supposed to happen or what can be done on these accounts that is poor management
