Cell C terrible service

I am shockingly disappointed and disgusted by Cell C. We recently moved to a Cell C Lte package and for the last 2 months have enjoyed the service. In the last week suddenly our Lte stopped working properly, only to discover that suddenly Cell C no longer offers LTE coverage in South Africa and all contracts have been terminated. No tell me how is it possible or even legal to terminate a service without proper notification...or 30 days notice. Cause when you wish to cancel a service with them you have to give them 30 days notice??? Were is the fairness? I am disgusted beyond belief.
