Poor Service

I am very disappointed with the service I’ve received from Telkom recently. I took out a mobile contract (upgrade) with them last year. The package included free Telkom to Telkom mobile calls. But am unable to call certain Telkom numbers and have reported this several times. I initially lodged a complaint about this around September/October last year. I need received any feedback instead I had to keep calling them reporting the same matter. And now recently the last person I spoke to indicated that the query has to be escalated and they will assign a technician and that I should expect them to get back to me within 48 hours. And it’s been over a week now and they have yet to contact me. Meanwhile I have to pay every month but I’m not getting the full benefit of what was promised.
