Accounts Department - Useless

Account Suspended - I have been a client for more than 10 years and for the first time ever I made an error when doing a payment. I used the wrong reference number. I contacted Vodacom as they said my account was in arrears on the 8 November 2023. I explained to them the story and they said they would rectify it. They gave me an email address to which I had to send the proof of payment to. Which I did immediately. I received an automated email with a reference number which stated they would contact me within 24 hrs. On the 13th they only responded stating it was received and sent to the accounts department for allocation. Today - 15 November 2023 my account was suspended due to nonpayment. What happened to 24hrs? Your data only lasts for 30 days but you are cut off even though I did what they told me to do. Now I have 3GB data expiring and I cannot use it because they cannot update their system in time. How much time do you need???? At this rate there is no point in having a contract anymore with Vodacom as their customer service is nonexistent. Phoning them you are sent from person to person stating that unfortunately they cannot assist you. SO, TO WHO DO I NEED TO SPEAK TO? As if no ever made a payment mistake and this is a new process.
