Ridiculous Customer Service

Vodacom fibre has the worst customer service and your agents are so ***********. When I initially app**** for fibre installation I requested that my debit date be the 25th of every month, however, someone decided to make it the 1st of every month. It came to my attention now that I am being charged an extra amount when they don't find funds on the 1st. I requested for a change in debit date to the 25th, that service request was not executed. Just absolutely ridiculous, I end up having to pay extra amounts and this has had a negative impact to my credit score. I requested for a cancellation a month ago and that service request is still pending. I cannot get any form of reasonable help. This is just ridiculous.
