To stop auto renewal in another mobile number from my credit card

I recharged 5 GBP to another mobile on 6 July from my credit card. Still every month this amount is deducted from my card and for successive two months it cut. I want to stop this auto renewal. However I don't have contact with that person now.

Mahmud509 If you have topped up another persons account with your card but no longer have contact with them you'll need to speak with your bank about stopping the payments. Lebara customer support wont be able to make any changes without speaking to the account holder due to security reasons.
