VODACOM loyalty does not exist

I have been on the phone today for three hours to get assistance from Vodacom. i was in a store yesterday to upgrade my contracts and was told that my account is in arrears and that i would have to sort it out with Vodacom. As i have already paid my account, i called today and was told that the money is showing from last week 26/02/2020 and that they would allocate it on the system. I then proceeded to cancel a line for a sim card that I do not have and to give notice on one of my contracts. After being cut off, referred to other departments, being told to call another number for almost 3 hours, i was finally told that no one can assist as my account is in ARREARS and once i have paid they will help me. I explained the "allocation" thing to the consultant and he said that i was to then phone back on another day once accounts and done their thing. My question is this; Which day will this be and they will then penalize me for not giving 30 day notice. i have now wasted valuable time and been embaressed in a store when they announce to all that i could not upgrade because "MY ACCOUNT IS IN ARREARS" Really, after being a loyal customer for more than 20 years.
