City of Esat Point

Im going through a similar ordeal with the city of East Point. I have a salon in EastPoint which opened up in Jan09.I had to pay 1500.00 down for a deposit because the former tenant don't pay there bills. East point don't send me first bill until june which was 843.00 for Jan-May and a week later a bill for month of June which was a 453.00 All was due 1296 at thAt time. I try talking and working out a payment plan. Which we did I was paying 400.00 a week for 3 weeks to pay off the but was not able to pay the whole amount I paid 1228.00 of the bill. But East Point could not tell me why the bill was only 200.00 a month at first and now 400-500 a month. But i paid it. The next bill came out and the chage me a penalty of 50.00.From 68.00 I left unpay but on the bill it clearly say that you will be chager 10% of the remian bal but how you get 50.00 out of 68.00 that is not 10%. But East Point have no anwers for me. And Now this month they chagre me for Trash $168.00 saying they was suppost to be charge me But was not. Who Fault is that you all bill is messed up.Trash servier is 24.00 a month no matter if they pick up your trash or not If they pick it up its 36.00 a month.The bill is from Jan until Now Sep. Im to the end of the rope with East Ponit. What to do
