Data lost within 10 minutes after recharge

i bought 250MB on the 19th feb now its been 5 days and still have no resolution for this simple case. after purchasing the data i started getting sms that my data has been used up already within 10 minutes and no application was running on my tab 4 7\ . went to the store they did not see anything on my account they logged a case. Nobody contacted me until i called back only to be told i will get the back then after 15 minutes was told another story that i will not get refunded for my data as i used it. the time intervals shows clear that my data was depleted at 11h05am not 12h20pm and they can not give me the raw data i want so that they can show me which url my phone was under. i do not need this time interval sheet you guys kept on sending me. Telkom if you can not give me the raw data give ME BACK MY DATA. Case Number: ***9"
