Billing issues

I was pro,ised a waved installation fee and I was lied to, I have a copy of the whole conversation the fee was supposed to be taken off within a couple of days so I dont end up paying the $100 I am living in low income apartments and am disabled the only reason I agreed to sign up was because I was PROMISED the installation fee will be waved before my next bill. The tech had to come out because when I moved into my new low income apartment all the cable wires were torn out. They said there is a person working on waving the fee as we chatted, and now I am getting a bill for $156. And on September 21 when I only got my internet on the 1 of september? I dont get my social security check until the 1st I specifically waited to the date I can actually pay my bill not before to request internet service/ This is NOT OK and if this is not fixed and if my credit score or my good standing is ruined because of your techs LIES I will report this and I will tell everyone to never truist xfinity or comcast. I told the tech I am living on low income and moved into low income apartments and he shafts me like this"?> I will NOT LET GO and I will NOT forget. I am looking for another company. I will cut you off if you try to charge me for the installation that I was promised will be waved and on a date I can not possibly pay. I am not getting disability twice a month, and I often hyave to chose to buy food or my medicine, I only get $841 for rent and ALL my bills low income apartments are not free you have to pay rent more affordable but you still pay, and electric and water are not free, and my phone is not free, which I need because I am very ill and need to have contact with doctors, but internet is essential these days, and I need a decent speed so I agreed to get the $55 a month for 5 years, however there are just many companies out there now, comcast no longer has monopoly that they can terrorize their customers the way they used to. I will not stay with frauds and liars. SO please, fix this. I am going to check in 7 days if my bill is still the same, I am cutting off your service. I just dont have this kind of money. I would rather have no internet than be bullied and have overdrawn bank account and have overdraft fees and be drowned so deep I will never get myself out, because you lie and trick people. I will write to the newpapers and I will publish my chat with the rep and his lies if my bill is not switched toi the 1 st oif every month and the $100 installation fee is not taken off as promised before my bill is paid ON THE 1st of every month and NOT before.
