Mtn

I would like to know if anyone else is having this issue with MTN. I paid my account on the 6th April but received a message of termination of services on the 7th after which I called in and they said we will make an arrangement until the 9th to allow for the payment to be cleared, I then received confirmation on the 8th of payment then on the 9th they send a message again as attached that I haven't paid and my ph will be cut. I'm so confused that a world renoun company cannot account for their clients payments. Really disappointed.
