TSTT is re­bat­ing cus­tomers af­ter a soft­ware glitch that af­fect­ed thou­sands of mo­bile sub­scribers.

The com­pa­ny is giv­ing Bmo­bile cus­tomers free da­ta be­tween 1 pm and mid­night to­day, Oc­to­ber 15, as it works on re­solv­ing the prob­lem.

On Tues­day, a soft­ware prob­lem caused in­cor­rect charges to be reg­is­tered against cus­tomers' ac­counts when­ev­er they used da­ta-re­lat­ed ser­vices on their mo­bile de­vices. It al­soaf­fect­ed their abil­i­ty to make calls and use da­ta ser­vices.

TSTT's tech­ni­cal staff is work­ing with its in­ter­na­tion­al ven­dor to pre­vent the is­sue from re­cur­ring, the com­pa­ny said in a re­lease yes­ter­day.

It added thatthe com­pa­ny al­so au­dit­ed its records to en­sure that all af­fect­ed cus­tomers could be iden­ti­fied.

"The re­bate process got un­der­way at ap­prox­i­mate­ly 10 am this morn­ing (Wednes­day) and the com­pa­ny es­ti­mates that all cus­tomers will re­ceive their re­bates in less than 24 hours," TSTT said.
