MTN making me pay for a service they are not providing

Kindly advise how far my below query is? On the 15th of May I sent an email after having spoken to a consultant about my Wi-Fi connection being off.

I sent the POP on the 15th of May to ***. Ref used as per POP is 0737****52. The consultant who took my first call was aware of this mistake then told me to send through the POP which I did however I still did not have internet for the whole month of May.

4th of June after not seeing a debit order go off I then again made a manual payment for the Wi-Fi and sent through an email on the same day to *** Ref used as per POP is 0737****53 . I still do not have internet because now I’m told the May payment has still not been allocated. How long does it take to allocate a payment? I wonder. No im done with these people . Previous *** No Wifi connection for the Month of May and June Current ***
