Disappointed!!!

Ever since my uncle left Telkom as the CEO, the service has gone to the dogs. I took up a second contract with Telkom in October and I was billed R1149, mind you my account always has funds (invoice came back “payment: thank you”) , an extra 99 was charged (Lord knows why because the debit order was not returned and payment charged was recieved ) total due for November was R1248, indeed this was debited by NUDBET (Lord knows why because every damn time, my account has sufficient funds) I have now received a statement for December and the total due is R2397!? Someone please make it make sense because I will not pay this amount!! What is it for!? and NUDEBT is a collection service which implies that you’ll have somewhat been unable to run debits from my account ? This is nonsense!! I ALWAYS HAVE SUFFICIENT FUNDS IN MY ACCOUNT AS I KNOW THAT I HAVE THE LAST DEBIT ORDER DUE BY THE 25th!!!!!!!!!!!! PLEASE CALL ME TO SORT THIS NONSENSE OUT!!! You’ll cannot decide to just debit those 99 as you’ll please and you’ll absolutely cannot charge double due to a lack of interglacial support and precise reporting between TELKOM AND NUDEBT!!!! Sort this out ASAP as it is affecting my credit score!!
