Webafrica charges

Contract was cancelled end of May, so provided 1 month notice for a month to month service. I have been charged a cancellation fee. Are you serious Webafrica!! A cancellation on something that is NOT a contract?!?! So basically no matter how much notice is given you are still going to charge the customer a cancellation fee. Is this even legal? Your WhatsApp line cannot provide anything in writing from me confirming the acceptance of this charge or a recording but instead tell me to read the terms and conditions on the web page!!!! Then you also have the nerve to charge me for a router that I don't recall having let alone used. You make no contact with me as per your cancellation email to provide details of where to return said router. Based on this and the information I have passed on to advise that I have been using my own router, the charge for a router is quite a surprise
