Account debited with 3 premuims only one Policy

We requested travel insurance on the 12th of June 2015 the premium being R571.00. My account was debited with the R571.00 plus an additional amount of R1142.00. The Consultant was Bester Moyo who confirmed that the R1142.00 would be re credited to my account the next day. I subsequently had to forward a copy of my Nedbank statement to prove the triple debit. But still to no avail. Every time I phone I get shunted from pillar to post ,and remain out of pocket. Policy Nr NED601735CSA
