Impossible to cancel subscription

I have 2 properties of which I lease one, I have Internet subscriptions at both properties with Webafrica. The lease is expiring soon and I need to cancel my subscription, apart from that I had no Internet service at this property for more than a month for some unknown reason which they can't or don't want to fix. I went onto their web login/cancel subscription app and app**** for a cancellation and also told them about the problem I am having with service at this property. Junade Porsaitides then got involved and promised to get it fixed asap and promised discount and everything is going to be peachy. Needless to say that nothing happened. If I now try to get my service cancelled, they say they cannot help me because I must contact Junade who is also just promising and nothing is delivered. I sent her a mail it comes back saying that it does not exist anymore. I will now be forced to cancel both my subscriptions and if need be I will cancel my debit order. I will never in my life have anything to do with this lot again.
