Valued client?? Realy??

I am upset and disappointed at the same time. I constantly get calls from Telkom telling my I am such a loyal client and they want to thank me by offering me a new line and contract, of which i decline cause I do not need it... The problem however is with my account. I always made payment on time on my account for the past 3 years. Last month my Debit order did not go off due to insufficient funds. I immediately made payment the day after the Debit order was meant for. This was my mistake i do agree. Now when I revised my account statement I am being charged +-R200 due to the debit order not going off. Now I wonder how valued should I feel as a client?? I pay my account every month. Since 2015 I have had an account with Telkom.

Do they realy need to make the extra +-R200??

Not feeling really valued as a client now.
