Telkom internet unuseable

Dear telkom. I have had issues with my internet for the last 3 months. Before that it was working perfectly and I recommend it to all my friends and family. For the last 3 months my internet has been unusable. My ping is fluctuating to as high as 3000ms. Download speeds drop to 0.12Mbps. I have a caped wifi broadband contract and im using a huawei B315 router that was supp****. I have 4 bars to full signal strength all the time. All that has neen done so far is that they tell me to reboot my router or set it to 4G only. None of this has any affect on my internet. Some days it might work perfectly for a hour or two.

I am fed up. I pay my monthly fee. The same amount evry month and i expect my internet to work just like it did before 3 months ago.

There a so many people conplaining on the facebook page but this just gets ignored.
