Terrible service, no feedback & communication

Telkom decided to cancel & discontinue my landline. No communication, statement etc to notify me of their decision. I visited the store and they told me to send a call back message on their tablet. an agent called back and I had to be on the phone for an hour and the matter was not solved. Today 9days later I called 10213 as per the instructions and the phone got cut off and they dont even bother to call back, Such an inconvenience especially when the landline is used for business
