Ridiculous service worst network provider when it comes to customers services

So i missed a payment for February 2020 beacuse i transfered the amount for my mtn account to the wrong account and. Only found out later. So at the end of marchh i made a payment of r250( 23rd)and then later r530(24th) to cover up for the missed payment as my monthly istallment is r399. I stil receive an sms to say i need to make an urgent payment if r252 to reconnect my services i didnt see the need for it but i later made the payment of r252 on the on the 31st till now the 1st payment of r530 hasnt been allocated its been 1 month n i have now made payment for april n may already of r550 beacuse i would be in credit frm march but still no joy.
