******** debit order!!!

A consultant (Thembeka Mbata) called me from this company in April and explained their services to me, she sent me a contract that i was supposed to sign and return to her but i ended up not signing up with them, i did not sign the contract. To my surprise my account was debited this month with an irreversible amount of R1250.00 but i did not sign the contract, this is ******** and i request you return my money and stop debiting me with immediate effect. Hello peter please assist
