Cell C is committing *****

I don't understand what's going on... a Cell C rep called me a few months ago telling me about this service of theirs. I agreed to have it added to my account. Since signing up I have been unable to benefit from the service / service has not been delivered as the app required to utilize the service has not been updated by them since November and the login page doesn't work (telling you the email address is incorrect when it's asking for a cell number). If you try the reset password route, it tells you you're not an existing Cell C customer - yet I can login to the official Cell C app. Customer Support simply refers me to the GetMore department, at which point the call drops every time. If you call the number directly - a poorly ****d recording plays that is clearly supposed to mimic a poor signal connection, because there is a lot of silences in between syllables. You know it's **** though because it's not like the words are broken - rather, after the silences, you hear the words completed. So it's like "Thank" silence "you" silence "for" silence "call" silence "ing"... etc. plus it's INCREDIBLY slow. I contacted their WhatsApp account, upon which someone who could barely write in proper English gave me a **** reference number stating my case was already logged 3 days ago. Impossible - I never logged it. But I tested the reference number by calling Customer Support and Cell C themselves claim the reference number doesn't exist. Now their WhatsApp service is just not answering my messages. I want a refund for all months paid or I am cancelling my monthly contract debit order and you will miss out on all contract payments, not just the R60plus you are *****ing from me every month.
