I would like to write a review about Old Mutual

I would like to write a review about Old Mutual. I have been receiving Debi check to my account for an old mutual debit order. I do not have anything with Old Mutual. I went to the Old Mutual office in Menlyn and it shows that I have nothing with Old Mutual. I don't know how to stop this Debi check and debit order. This is a *****ulent transaction and I meed to stop it as it is messing with my ITC.
