Axess wifi issues port elizabeth

I had a contract for fibre with axxess cape road. I decided to cancel the fibre as i was told no contract. Month to month. I used the whats app chat provided to try cancel. I was advised despite supplying acc no all relevent info i must use the app. I explained i am technicaly retarded and that was difficult hence my advising of cancellation in writing. The responce clearly written on a pice of paper was you must use the app. I advised you are here to help not read a reply from a pice of paper with a few phrases. No help offered. I waited a few days tried again on whats app. In writing advising i wish to cofirm my canellation. Again the pice of paper spoke. You must use the app. I explained again. I have for a second time advised them of my cancelling in writting. Tpaper got angry said you must give 30 days notice. I was told no contract???? That requires a contract. They advertise no contract. Strange. I get an invoice we cannot pick up your payment. Should we not recieve payment will terminate the service. I reply thank you i tried to cancel twice. Next thing the paper answeres you must use the app. I explained it did not work for me. Then the paper says cancel by email and 30 days notice required. But no contract advertied. They cutting me off????? No one said cancel by email. Whats different between an email or whats app. Its in writting with all relevent info provided. Please be cautious this is false abvertising and the pices of paper responses are very limitted and not any effort to help a perdon at all.
