Vodacom - please assist with call reference ***0

I have been a loyal customer of Vodacom for years now and my account is always paid up and never have been in arrears. It has now happened that I have reached a certain set credit limit and they soft lock my phone every morning at 07:00AM I then have to phone them EVERY morning to remove the soft lock. They have logged a call for me – call reference ***0 Nothing has been done to fix my credit limit permanently - you can also not email them or use the chat functionality as they have disabled email and chat and you must phone 111 Customer care. Please can someone sort out this mess for me. This is urgent and I do not want to phone Customer care every morning at 07:00AM to unlock my soft locked lines. Is this how you treat a person that pays you nearly R100 000 a year in mobile costs? Can a Service Delivery Manager please get back to me, not a 1st line agent or Call centre agent but someone who deals with Service Delivery please?
