Shocked about the response we get!

Shocked about the response we get! We skipped one payment end of Jan and made a manual payment first week of Feb. After we made payment they cut our lines for 3 weeks. End of Feb we made another manual payment as Telkom informed us we have to as the debit order will only be back in working order from end of March. They still cut our line and it takes 14 working days to be restored even after sending proof of payment and confirmation from the consultants that payment was received. End of March the debit order was back - they still cut our lines even though they have received payment. Yesterday we see we have been cut off again - debit order went through. The response we get is that "we are being punished due to the one late payment, so even though we pay timeously, they will cut our line". That is disgusting service after being loyal clients for 10 years.
