Highly angry and disappointed

I have had a vodacom contract for many years and have made sure my account is paid. For the first time in years my debit order did not go through and they want to charge me R100. At no point in all the years have i ever been told there is a penalty fee.

I feel this is wrong and if they want to charge fees then i should have been notified of this which they have NEVER told me about the charge.

I have been a very loyal customer with vodacom since 2011 and i do not agree with the charge since i was never told of it.
