Telkom is the Pits!!!!! Dont ever join Telkom networ****!

I tried to top up my wifi last month on the 19/03/2018, I tried to buy 10gigs for R249.99, it did not go through on the mobile app, I tried again and got another error message to say it did not go through, there was an error message. So I left the wifi off because the top up did not go through, when I get my bill at the end of the month I'm charged for topping up twice, bill is R500. When I call into the call centre, they tell me once the top up is done its done, they cant refund it, I told them I got an error message according to me, it did not go through. Now its the 24/04/2018, I have been trying to get through to the call centre this whole month, no answer, I get through today and they do not want to help me. I mean you tell me, how do you pay R500 for an expired 40gigs of data that you never even use, because of Telkoms app being under construction and they don't even notify their clients. I was told my query would be escalated and it will take 9 days, what's the point of an escalation if its gonna take 9 days, the service at Telkom is pathetic, slow, doesn't work, its terrible, im so mad right now I cannot pay for something I did not use and especially 40gigs worth of data, so its like ****************, I must pay for something that's gone. Telkom got time to play I've never received such **** service in my life!!!!!
