Debit order running on wrong date

My debit order I signed with Multichoice on the 30th of May 2017 clearly states that, and I quote "MultiChoice Africa (Pty) Ltd will charge my account on the first of each month".

They always collected on the 26th or 27th of a month which did not worry me, cause I get paid on the 26th, so money were available for the debit order to go off, but this month, they decided to run the debit order on the 25th, resulting in FNB charging me a debit order refusal fee of R100, as if we're not paying enough for DSTV and standard banking fees.

Now, the question/remark to Multichoice: What are you going to do to rectify this situation and pay back my R100 penalty occured due to your error? (I know, I won't pin my hopes on any sort of feedback, what to say a credit of undue costs incurred due to Multichoice fault)
