Dissatisfied customer

Very dissapointed in telkom. Recently changed my banking details. my bank sent telkom my updated banking details however they rejected that request. I called their call center an agent advised that I could to a manual payment which I did in dual time 2 days after my normal debit order goes off. I get an invoice now with an additional charge of R202. 70. I contacted their call center I spoke to a lady who advised that they charged me for a rejection and I immediately lost my mind because telkom rejected my bank to update my details now and now they charging me for going into a bank account which I told them they not going to get money from worse I have made a payment 2 days later which was in the period of that month. The consult told me she can't even open a complain about this. What upsets me the most in these difficult times were money is tight telkom wants to ***** from the poor.
