Every month, a small group of prepaid customers were suspended for owing three cents, a rounding quirk nobody could explain, and nobody had claimed as their problem to solve. I spent the time others hadn't to find the actual cause, and found a fix cheap enough that no one had a reason to say no.

A small group of Prepaid customers, on basic phones with no data plans, were getting suspended for owing three cents, the result of a stray data charge the day before their billing cycle reset. It looked like a minor rounding issue, but for the customers it happened to, it meant a real service interruption and a call to Customer Service to sort out something they did not cause.
The cause touched three different teams, technology, device hardware, and network, and no single team could see the whole picture on their own. It had been a known issue for years, but because it never landed clearly on anyone's desk as their responsibility, it just became something Customer Service knew to expect and explain away, one call at a time.

A problem that has been unsolved for years usually is not unsolved because it is unsolvable, it is unsolved because nobody's connected the pieces yet. I brought together people from technology, device hardware, and network who each had part of the picture, but no reason to compare notes with each other.
Once we did, the pattern was obvious. It just took someone treating a three-cent issue like it actually mattered, like it mattered to the impacted customers.
A small group of Prepaid customers on basic phones were getting suspended over a $0.03 charge that hit the day before their billing cycle reset, a rounding quirk that looked minor on paper but caused a real service interruption, and a call to Customer Service, every time it happened.
I gathered the data, examples, and specific accounts affected so the problem was no longer just something Customer Service knew to expect, it was something with real numbers behind it: over 1,000 calls a year, and $18,000 in combined cost between the adjustments issued and the Customer Service time spent handling them.
The cause touched three separate teams, technology, device hardware, and network, none of whom could see the full picture alone. I brought them into the same conversation with the data in hand, so solving it stopped being a vague, ownerless problem and became something concrete they could actually investigate together.
Once we identified the pattern, three calling plans with no data allotment, prone to stray charges, I proposed a fix that cost nothing to implement: a small hidden data buffer added to those plans. I brought it to Marketing, the only team that could edit the plans, and got buy-in before it ever went live.
After launch, I had the Prepaid team track any customers still affected to confirm the fix was working, and kept an eye on previously recurring accounts. The result was a 95% reduction in impacted customers and about $18,000 in yearly savings, and once the numbers held steady, we scaled back monitoring to a quarterly check.
The fix cost nothing to implement and reduced impacted customers by 90%, saving roughly $18,000 a year in adjustments and support costs combined. More than the savings, it closed out a problem that had quietly frustrated customers and support teams for years simply because no one had connected the pieces, proof that taking the time to put the pieces together can make a real impact.
