Network problem

I have a very very bad experience 😭😔😭 with Telkom both their fibre and mobile, they always don't have network, you will buy data and will expire without even using it 😔 or out of 1,5 GB you will only use 200mb. The worse of it is their fibre I end up cancelling it they gave me cancellation number but they still billing me on it after cancelling it worse worst ever network. When calling their contact centre they are no use when going to branch they told they don't deal with customer complaints need to call 10210 but still no help in their call centre they just in hurry to cut you off. They don't wanna listen to your story but they want you to listen to their story... I'm so sorry so not happy with Telkom I will never ever recommend it to any one worse ever network. Now I'm registered with another ISP but they expect me to pay for the same thing which they can't deliver. What makes me mad is that they still billing me for something they are not providing. Telkom is a day ******* shame.
