INCORRECT INSURANCE PREMIUM BILLING

In February my debit order for the home loan account increased from R6011.06 to R6157.80 with no communication as to why? I called in the home loans department to be told that my premum for life cover on the bond account has increased from R180.69 to R328.91???? When i questioned the reason behind the increase none of the consultants could explain the reason and was told I would be refunded in February already. It's now a month later and none of that refund has been processed. Today I check my bank statement only to realise that the ame amount has been debited off my account again!!! I called in the assurance dept and spoke to Timothy who told me that there was refund request logged but "pending". A whole month pending t be authorised!!!! I then asked why did they raise the same premum again and he said it was reversed back to the original premium of R180.69 but that's not what was debited in my account.

Can I please have this rectified and both my refunds processed back into my bank account and not the Home Loan account ASAP!
