An internet user surnamed Bai has told local media that online travel service provider Ctrip.com not only loses users' accumulative mileage records, but also refuses to take responsibility for this.

In May 2006, Bai reportedly was advised by Ctrip.com that Ctrip.com would provide the mileage accumulation for its members. Since then, Bai never claimed the mileage himself, but later in May this year he accidentally found out that his latest flying was not recorded by Ctrip.com.

After Bai contacted Ctrip's Client Service Department about the data loss, the company denied there was something wrong with their service, and transferred Bai to Ctrip's Membership Center for a solution.

Regarding Bai's question, a representative from the Membership Center of Ctrip.com said mileage accumulation is a value-added service provided to Ctrip members, but Ctrip.com won't be responsible for the consequences of any problems of the service.
