Worst company ever. Back in 2014 I moved and called pwc to have my services disconnected. I paid my remaining balance and they said everything would be turned off. 2016 I move back to Fayetteville and they tell me that I owe over $1,800 towards that previous residence. I had to pay a large deposit, plus the $1,800 just to get service at my new house. I am under the understanding that all customer service phone calls are recorded, but yet when I ask them to look up my service calls from that address they give me excuses. Clearly so they will not have to admit their mistake. Why in the hell would they let someone go that long without paying anyway? If I owe $300 for my business account and I'm 4 days late they disconnect me, but they let some leech in my old house go to $1,800 without a disconnection?...This makes no sense to me. Worst company ever.
