Means of communication is frustrating

So I arranged with Web Africa my line to be canceled on 11 June, because we have been experiencing connection issues for about 3months and nothing really is done to have it sorted out. Any way fast forward to today 13 June, line only canceled now and not yet released, I am left without internet and the new ISP cannot do anything until Web Africa releases on their end. Getting a hold of them is also a hassle on Whatsapp and their portal, communicating with them is extremely frustrating. It has been 3days now and I must follow up with them constantly regarding the release of my line.
