U.S. Cellular / United States Cellular review: Billing/refunds overpayment

I was recently triple charged due to a billing error on US Cellular. The amount of overcharges was almost $500.00. I called US Cellular when I noticed the error and it was stilled pending payment. The customer service representative I spoke with told I would have my refund in 12-24 hours. When this did not happen I called US Cellular again, I was told that since the payment had now gone through I would need to wait at least 30 days for a refund. I stated this was not acceptable and I need the money to pay my other bills. I was told it could be expedited if I went to one of their stores with a copy of my bank statement showing the extra charges. I went to store I was told it would take 7-10 days for refund. After that time was elapsed I called US Cellular again and was told the same thing the first representative had told me, I stated all the previous things I had done per their request. I was then told I would have payment on a specific date. This did not occur. I called yet again and was told it would be another 7 days (this will be the 30 mark from my original complaint). Still no money, and no accountability except for passing the buck to the “ billing resolution department “ saying that they could not/would not expedite my refund . My bills are stacking up, luckily my ex-husband lent my some money so I stayed current on my rent. I’m looking forward to ending my 20+ year relationship with US cellular, I’ve had enough.
