Not Happy

Against many peoples advise, I thought i would give Telkom a chance, I am currently unemployed and need internet to be able to apply for jobs online etc. We bought a WiFi router through them which we received on 26/6/2020. On 29/06/2020 the entire 40G bundle had dissapeared - not being a IT buff, i did some research and found that my router is being "Port Scan Attacked". I waited until today to log on with the new month data and do some fishing, it is happening again and the bundle is depleting very quickly - I call Telkom and I get transferred from this department to the next and out on hold for 30 min with absolulty no answer and now no airtime, how is this acceptable customer service? I need help but they don't take your calls.
