Telkom is the worst service provider in the country

Telkom is a terrible service provider,. I app**** for a telkom line which took 3 months to arrive, then they insisted I pay by debit order, even though I explicitly told them I get paid weekly. They then ran the R200 debit orders during the week when I had told them I get paid weekly, and with the unpaid debit orders they charged me R200.00. I was paying my R200 bill by EFT, but because they were running multiple debits they told me I was owing R600, whereas I had paid my monthly due amount. I called Telkom billing regarding this issue for them to cancel the debit as I was paying via EFT and was told to go to a Telkom branch, the branch then told me there's nothing they can do and to call Telkom billing. Now they have placed me in the credit bureau for owing R2500 that was all accumulated by them running multiple debit orders on dates not stipulated.
