Stoper order mess

I am disgusted in Incredible connect head office. on the 15 of September I made to additional payments to Incredible connect over and above my debit order. I then received the statement for October and see only 1 stop order payment on the statement. I then email ***. which Lionel Evans then response, shame poor *********** person. he sends me a statement, but the additional payment still doesn't reflect, and this is what he says n the email: Good day Mr. Davids,

Please ignore the previous email l sent to you as the 2nd R300.00 still does not reflect although the balance does decrease by R600.00. The error is within the statement print logic. I have requested the IT department to assist and will forward you a corrected statement.

Regards Lionel Evans Customer Account Management (CAM)

after a sent him a response to this email he then does not respond to me since the 25/10/2023. I tried calling their call center. Once you explain to the agents they then disappear on the system. I don't now what to do as my last payment must be in December.
