Verizon and Sprint customers are due some money, but the deadline is nearing to get your refunds.

NJ.com reports subscribers to either wireless service have to file a claim to get their share of a $158 million "cramming" settlement, and must do so by Thursday, Dec. 31, at the latest.

Verizon Wireless and Sprint Corp. agreed earlier this year to resolve nationwide allegations that they engaged in mobile cramming, which is putting unauthorized third-party charges on customers' bills. Charges ranged from $0.99 to $14, averaging $9.99, for services like premium text messaging, including horoscopes, celebrity gossip, sports scores and flirting tips, or ringtones and wallpapers they didn't order.

Verizon got 30 percent of those extra fees and Sprint's commission was 35 percent, according to The Consumerist. Both agreed to require customers' approval in the future before making any third-party charges.

Customers will receive refunds through "redress" programs supervised by the Federal Consumer Financial Protection Bureau. New York Attorney General Eric Schneiderman estimated 2 million New Yorkers would be eligible for refunds when the settlement was announced earlier this year.

Verizon users can apply for their refund at cfpbsettlementverizon.com, and Sprint customers can apply at sprintrefundpsms.com. Submissions must be sent on or before Thursday. Former customers may be eligible, too.

Refunds will be sent to qualified applicants within 90 days.

Both companies will also pay penalties to the FCC and every state, including $340,301 from Sprint and $453,900 from Verizon to New York.

Last year, AT&T paid $105 million and T-Mobile USA paid $90 million to settle similar accusations of cramming.
