Telkom billing issue still not resolved 5 months

Telkom failed to rectify contract. In March 2019 I upgraded my cellphone and requested a data contract. The phone worked fine on all networks but the data contract doesn't roam. I instructed the person at the Telkom shop clearly that the data contract must be able to roam as I live in the rural Northern Cape. When I got home, the data sim didn't work. I immediately notified the person en she promptly promised to rectify the issue. After many emails, online logs and another 2 visits to Durbanville Telkom Shop none has been resolved.
