You promised to call and Nobody called

I logged a compliant on 12 Oct "I regret the day I did business with Vodacom". You promised to call me but you did not - I'm not sure what do I need to do now. I am yet to receive a call from you about my query. The only call I received was from a Consultant asking me when am I going to settle my arrears amount. what arrears amount because my query is still under investigation? My account is in arrears because you guys are billing me incorrectly. I have submitted the required documents to your ***** Dept - I have not received feedback let alone an acknowledgement email. Shocking service!!!

I cannot do business because my devices are blocked. I don't want to hear you guys tell me I must pay end of the month for the service that you discontinued.
