MWEB BILLS CLIENT BUT DOES NOT SUPPLY THE SERVICE

I had an MWEB LTE contract. Without warning, on 27/12/2021, they disconnected my SIM card. No-one responds to my queries, and they still continue to bill me for a service that I am not receiving. I've been with them since their inception, but I no longer trust them. BEWARE everyone. Their business practices are *********.
