Disappointment about arranging payment

I'm disabled, my son is in the military overseas (he's on my wireless plan). My wife lost both parents within the last 4 months and had to take leave of absence from work to care for them. I gotten behind on my bill. Due to things out of my control. Very disappointed and discouraged you would not work with me on my payment. I asked for 7 days (that's when I receive my monthly disability check). I have been with ATT my whole adult life (I'm 52). I even told ATT I could pay a portion of my bill on Thursday of this week (a relative was going to help me out). And the remainder next week. ATT would not work anything out with me. Now my son is on the other side of the world and is not going to be able even communicate. Come next week after I get my bill paid. I will be going to another carrier. Thanks a lot for showing you really care about your customers.
