Bad customer experience

My wifi service has been suspended due to non payment, firstly they debited the amount successfully on the 15th november and my service was on u till today they suspended it telling me I have not made payment so for using the service for over 2 weeks they debited a full months payment after speaking to their customer service over WhatsApp which is not helpful at all I still have not received clarification as to why it has been suspended if I have not used the service for a month, no empathy towards their customers or resolutions the agent that was dealing with the matter had no clue what to do there's no escalation route to follow, he kept me on that chat for 2hours plus and then he ended the chat because he had no resolution for me I have logged a complaint doubt anything will happen with the complaint logged. I'm now sitting without a service which was fully paid for.
