Day light *******

Bought a cell c home connet sim selling for R60 prepaid it came with 10gig of data I used the data and I was happy the data until when I tried to recharge my account for the first time I bought R63 airtime recharded my account when I check my balance it R0,00 I then called the customer care I was told that my airtime was taken by my cell c subscriptions more than 20 of them taking about R1,50 a day. This sim card is still brand new why do I have so many subscriptions taking my money ? I want my R63 back
