BAD CUSTOMER SERVICE

On the 15th of December 2018 , i Called Telkom to get a reference number for my cellphone contract so i can make an EFT since my payment came in early and my debit order date is on the 25th of every month . I Went on the live chat on the 18th of the month to confirm if payment was reflecting and the agent adviced that it was and the was a short payment of R0.05 And i asked if it will be debited or i must pay it in and he adviced that it will b debited . On the 28th of December , i received an sms that the was a debit order of R305.05 and reversed it . I went on Live chat and we couldnt reach an agreement with the Agent ,i requested her to ask her Team leader to call me . The team leader called me , she had adviced me that the terms n conditions of telkom says I MUST BE DEBITED ANYTIME MY BANK ACCOUNT HAS SUFFICIENT MONEY EVEN IF MY ACCOUNT IS NOT UNDER COLLECTIONS! I asked her to send me the ts n cs as im not seeing that on the contract and she said she will log a case for Collections to call me since they deal with billing . 2 days later i received a ref number ( ********** 8) and still haven't received feedback . She also said the debit order went on ,on the 18th of December , which is the same day i made a payment . When i asked her why my Debit went on the 18th of December instead of the agreed date (25) She said THE SYSTEM PICKED UP ,THAT I MADE A MANUAL PAYMENT HENCE IT ALSO WENT THRU TO DEBIT. She said to me ITS ALSO ON THE TS N CS .The shock on my face . Now my other problem is I received my statement which shows that my manual payment was done on the 18th of R305 and on the 27th a debit order went of . My questions is Why have i been **** to by the Team Leader ?And why Im I Liable for a rejection fee of R294 where else an agreement i had with the 2 agents i spoke to on the 18th confirmed that . Credit my account with R294 and give me a settlement amount .
