Consumer Cellular began charging me for three lines of service before any of my phones were activated. The company started my billing cycle before I received their SIM cards for insertion into my phones and before I received a phone that I purchased from Consumer Cellular. Accurate mobile data records failed to update within a 12-hour time period. A one point, it took 7 to 10 days before my data usage statistics updated. Consumer Cellular blamed this problem on a technical abnormality with T-Mobile's cell towers. By the time the problem was finally remedied, Consumer Cellular users may have exceeded their data limit without knowing it. I signed up for three lines of "unlimited" talk, text, and data. When the "unlimited" 35GBs of data were used up, someone from Consumer Cellular added a pricey data package to my account without my knowledge or consent. Consumer Cellular deleted my voicemail account. I had to setup my voicemail again. Texting issues resulted in the delay of texts being sent for up to 2 hours. I had service with Consumer Cellular for 29 days before cancelling my account. A repetitive, on-hold recorded message advertises Consumer Cellular's satisfaction guarantee as follows: "Here at Consumer Cellular, we have always offered a 100%, risk-free guarantee. That means, if you are not satisfied with our cellphone service, regardless of the reason, you can cancel within the free trial period and pay absolutely nothing. You don't even have to pay postage to return your phone." There is no reference to any disclaimers within Consumer Cellular's recorded message. I received a bill from Consumer Cellular that contained incorrectly calculated amounts of service plan charges, fees and taxes. I spoke with several customer service agents and supervisors about my bill. No one from Consumer Cellular could explain how the total was calculated. Consumer Cellular employees would routinely use the phrase, "These are legitimate charges." One customer service agent made a claim that Consumer Cellular's billing department was incapable of making a mistake.
