Pathetic and useless service

Every month my landline has a cross-line problem. Where there is no dial tone. And if my number is dialed I reach someone else. My Internet connection is intermittent as well. Loses connection every 10-15 minutes. Today I went into the Claremont branch. There was no phone to use to book a technician. I couldn't even use theirs. They couldn't contact a technician for me . All I was advised was to report my fault by sms or internet. Which has a turnaround time up to 9 days. this is a monthly issue and yet it still not fully resolved. How pathetic can one leading company be. It's embarrassing. All I want is the services in pay for. A working landline and a solid Internet connection.
