Billing *****

I took a router in March this year 2024 I told them to debit on the last day of every month and they debited R357,71 who was prorated on 30 April 2024 They debited R252 on 31 May 2024 Mid May I contacted them to change my debit order date to the 15th of every month as my pay date changed so they said they will debit in July as they have already debited for June from my May salary On 29 June 2024 they debited and found no money in my account I immediately called them and asked them to stop debiting on the wrong date because they are ruining my credit score. They failed to debit for July and said the mandate has not changed they asked me to do a manual payment which I did on 22 July 2024 and on 25 July 2024 they debited R524 I called again and asked why they debiting when I’ve already paid the guy I spoke with said they may have had a problem with the mandate again and told me to reverse it so I did August 15 they did not debit and told me the debit order could not go through and I should make a manual payment I told them to stop making their technical problems mine and I was told to pay R733,42 including penalties when it’s not my fault the debit order did not go through.And last week I called the voice recording said I owe over R300 as I made a payment of R400 on the 9th August I never made any payments in August,something is amiss with the finance department please intervene I am extremely furious with Telkom customer service , just yesterday they sent me a text saying they have put me on the credit bureau this extremely infuriating!
