Can the some one help me

I have 2 contracts with Telkom 1st a router and 2nd a phone In September I received message saying my account is in arrears with R1035.38 which I did not understand when I contact the call centre they told me they debit my account on the 5th of the the month which I do not understand because because the 2nd contract is an add on to the 1st contract and the router does debit on the last day of the month and they do not take the 2nd contract. Okay on the 7th I made payment if R300, and on the 19th they debited R735.38 from my account. I called the call centre asked them to change the debit date of the 2nd contract and make it last day of the month, I even received a reference number, ********** , saying my issue has been resolved. Yesterday 01/10/2018 I saw they debit the 1st contract and not the 2nd contract not debited, what is going to happen now will they try to debit again on the 5th and tell me my account is in arrears again. I have been calling the call centre I had to wait about 36 minutes to get consultant and they could not assist me I asked why is that my account shows I still owe the R735.38 if it was debited she told me that has nothing to do with her. So what do I now. First the problem is why were the debit dates different when I requested for same debit dates. When I called last week requesting for amount payable to cancel the contract the first consultant told me I need to pay R5300, then yesterday I called again Kathlego told me I need t pay R3800 now and then when I asked him why the account was not debited for the 2nd contract he told he can not see that account, so where does he get the amount I need to pay if he cannot see that account???? I am really lost for words
