Worst Service and incorrect billing system.

I would like to share my disappointment with Webafrica with the type of service they provide you. Firstly, you can not contact them telepathically however only a chat line on whats-app. I did a change of ownership from the previous account holder 1st August 2022. The previous owner started his contract with their fiber on the 1st of February 2022 which means my fiber was already connected and installed when I moved into the premises. Due to unforeseen reasons I had to cancel the contract 1st of December 2022, giving them 30 days notice. In total the contract was up and running for 11 months. Upon my cancellation I was told they had to charge me a cancellation fee of a certain amount, however, on the 31st January 2023 they deducted the entire amount for 12 months from my bank account, Which was not the amount they provided me for the cancellation upon me giving my notice period. They incorrectly calculated the outstanding cancellation amount since I were already there for a few months. They also requested the rooter and all equipment to be send to them via courier, which I did, they collected all the equipment via a courier company. I have been on a whats-app chat line with them since 31st January for hours explaining the entire situation, no feedback, today again I had to explain the same situation again via whats-app where I was told their finance department will look into the matter. I still have not heard a single word from them. They are unwilling to adequately address the complaint. As mentioned the line was already connected and installed when I moved into the premises, so its pointless for them to charge me an installation/connection fee claw back. My reason for this review is to inform the public on the poor service they provide you and the fact that they deducted money from my bank account incorrectly. You can not email them, all their emails are a "no-reply" address. The only email address from them are what's on your monthly account. (***) How do you then get a query like this resolved if they do not even respond to their "whats-app chat line" after being told they will investigate the query. Will they ever respond is my question.
