WebAfrica are lost

I've canceled months ago and I am still being billed for a Static IP service linked to the fibre line. Their WhatsApp support channel has always been a pain to use. Their cancellation process was a slap in the face to a long standing customer from 2012, please return your 7-8 year old router which I've certainly paid off by now... or you get charged. New customers are all they want, old customers get taken for granted. Won't let you remove your credit card from the backend unless you first replace it with another. Backend is limited and you feel boxed in, backend support has never worked for me. I've remained calm through the whole drawn out process but bye bye WebAfrica, you have fallen far.
