Inflated Debit order by Capitec Bank

I have a loan with Capitec which is paid by debit order. After about 12 months paying by debit order correct amount, suddenly it changes by 60c extra. I queried it but never got answer. They just reverted to correct debit order and did not re-reimburse my money back which they deducted for 6 months. Now they have done it again.

Is someone *****ing my money or what. Computers take what has been fed into them. I dont know what else they deduct without me noticing. Please people check your debit deductions from Capiec Bank. Something is not right
