Horrible customer service since Afrihost take-over

Been a happy client of Home-Connect for years (whom I joined after I left Afrihost because of their horrible client service). And since Afrihost took over Home-Connect service is going for a dive. E.g., I was rehoming and wanted to continue my service at the new address. Logged a ticket on their "app" (which should not be called an app, because sometimes it works, sometimes it doesn't), but got no response from them. So I signed up with VOX in the end ... And now I'm trying to cancel my service at Home-Connect. But that is near impossible, it seems. Despite the fact that my contract state that I have to give 30 days WRITTEN notice of cancellation, they don't accept emails: It has to be done in the "app". I phoned to say that the app won't allow me to cancel MORE than 30 days before end of service, only to be met by an extremely rude operator. I insisted on speaking to a supervisor. Then someone said (not a supervisor) called me back a day later, only to be more rude than the previous person. I insisted again to speak with a supervisor, who was supposed to call me back. But nothing... My advice: Stay far away from this once great service provider. Their nr 1 ranking currently is not a reflection of what their current status is.
