Payment arrangement assurance

I contacted Xfinity to set up a payment arrangement. And the rep assured me that they indeed, set the arrangement and my service would not be disconnected. However, 2 days later it was disconnected. And I am being told I have to go into a store that is over 30 minutes away and I don’t have a car at the moment. I spoke with another rep and they kept telling me to go to the store because of an error on the account. I work from home and will face missing a whole days pay because of an error after being assured that a payment arrangement was set and I don’t have anyone to take me because they are all working. I’ve been a customer for years. And I’ve never had this issue before.

when I asked why, I was told there’s a error. And I clarified even if I was able to make that payment today. I couldn’t without going to the store. I genuinely am considering ending my service with Xfinity now. Over something that I was told “rest assured” it was fixed and service would not be disconnected.
