Over Debit on my policy

I had already had a policy with Liberty Life for a RA with a premium of R700 a month. This was with a previous Financial Planner whom later got promoted and was no longer going to be able to service me. So when I wanted to reduce my premiums I then contacted my previous Financial Planner whom arranged for Elroy to contact me. <br> <br> So we meant and I informed him i needed to reduce my premiums. He then brought me the paper work to sign which I did. However, now instead of the R700 being reduced to R500 Liberty instead debited an additional R700 from my account. <br> <br> Now, I have called, emailed and even placed a complaint through the Liberty website but yet I have still to be contacted by them and this matter being resolved. For a lucrative establishment like Liberty to try something like this has really disappointed my expectation in dealing with them.
