Bank Account incorrectly debited

It is for the second time that Hollard insurance is debiting my bank account incorrectly and I do not have an account/policy with them. They have debited my standard bank account with an amount of R 177.00 with reference ***G - ***5 this has cost me as I only had money for my assupol debit order which was going off on the 25th and now the assupol debit order returned unpaid due to insufficient funds in the account because someone fron Hollard decided to target my bank account again. The last time they did a debit on for BJ Ngobese, and I received an apology letter from Irma Roberts. I am ****ed off as I do not have a policy with Hollard and now they have cost me an unpaid debit order with the Assupol my insurance I urgently request someone from hollard to contact me. ****ed Off!!!
