AT&T Double billing,att submitting bill to collection agency after told not to pay incorrect bill by att Atlanta Nationwide

I was informed by ATT that I had to switch my internet service to U=verse or lose internet service. It was switched on 2/28/15. I was told not to pay my bill for the old service ( $31 internet service 2/1 through 2/28 and Home phone 2/23 through 3/22) until I would receive the Final bill.

My bill for the NEW service dated 2/28/15 was from 2/28 - 3/28 for U=verse internet and 3/1 - 3/28 for home phone which I paid on 3/24. My final bill dated 3/23/15 for the OLD service charged me from 2/23 through 3/2 for home phone and $31 for internet service 3/1 through 3/31 which was already included on the new u=verse bill and paid for.

I called att and after over 1 hour on the phone and being past around to different customer service agents, I finally talked to someone that understood the mistake made. He told me NOT to pay the bill until I received a new revised bill.

After 2 weeks, I started getting harrasing phone calls from a collection agency that I owed att $87.22 for not paying my final phone bill dated 3/23 on the old service.

After receiving my revised bill dated 4/23/15, I noticed that I only got a $29 credit instead of $31 for my old internet service . I was charged through 3/2/2015.

I called again to have it adjusted for the $2 double billing 3/1 and 3/2 for internet service, not addresing the double billing for internet service for 2/28 and home phone service  3/1 and 3/2. I was told that since my bill had been turned over to a collection agency, no further adjustments could be made and I could only deal with the collection agency.

I ask for a supervisor and was given the same answer. I refused to do this and said that this was not my mistake and att was fully responsible and as a consumer I was taken advantace of by double billing and falsly reported to a collection agency after being told by att not to pay my bill until I would receive a revised bill.
