MTN Prepaid Data Contract Nightmare

I have a Prepaid Data Contract with MTN. I pay in advance every month for my service. On 8 May 2024 I made the payment for June 2024. On 26 June 2024 I made the payment for July 2024. MTN suspended my service after receiving my payment on 26 June even though I have paid for the full month of June and it is not July yet. Then I had to make a payment arrangement after already having paid for July just to get my service activated for the rest of June which I have paid for in full on 8 May 2024. On 2 July my service was once again suspended. After contacting the call centre I was advised that my payment was late and service will only be reinstated on 1 August 2024. This is insane as this is a prepayment Data Service and my prepayment was made before 1 July 2024. Just wondering to I need to pay in July again for the August service seeing as I will not be having service in July which I have already paid for - I THINK NOT! In my opinion you are busy conducting business ********ly and you think that you can do so because it's a big corporation and what is one individual going to do? I am definitely not leaving this here MTN.
