Terrible Service!!!!!

I logged a fault with Telkom on 9 January 2018, which is still not sorted out!! My internet keeps on dropping, eg 22 times per day... I use the Telkom internet for work, and is absolutely ridiculous. I have called Telkom 16 times, spoke to two supervisors as I insisted, still waiting for return call (one call since Monday, 13 February, the other call this morning, with calls that lasted 75 minutes and 25 minutes each). This is the worst service I ever experienced, how can Telkom take 6 weeks to try to solve an Internet issue!!!
