Business ProfileforTDS

Last month (as of the writing of this, just last week) I called TDS customer service to report an unexpectedly high bill of ******. After literal hours on the phone speaking to different customer service reps a credit was placed on my account that did not show up immediately in the online bill pay system. I explained to one of the customer service reps that I was not willing to pay what was equivalent to 3x my previous bills to keep my account up to date due to their error and as the bill was coming due, I was not wanting to incur late fees for an issue not of my creation. She got snippy with me and told me that a late fee is only 10 dollars. After being asked to be transferred to a different service rep, I finally got some resolution and a promise of a call back the following day to ensure that the new amount due actually reflected on my account. I asked repeatedly if the double billing issue had been resolved and was told it had been. I asked what amount I should expect to pay monthly in the future and was quoted ****** + tax, this was in line with the dollar amount the adjusted bill ended up being, 166.01.This week I receive my April bill and again it is inflated to ******. I decided that I would not wait until closer to the due date to deal with this and spent the last 2 days calling TDS. Once again they adjusted my account but this time I was told that my new monthly charges will be ******+ tax or ******. No explanation was given by the first rep, the second rep told me it was a general price increase for services. How did this change from last week to this one?? Their math is not mathing and they offer no explanation of their adjustments. I feel so frustrated and annoyed, I was first blamed that the high bill was due to my account being delinquent, not true as I normally carry a credit on the account month to month. Then I was told it because of upgrades. I need this resolved. I do not want to have to call them every month.
