Telkom and their ****py service

I paid my bill at pick and pay on the 7th October Telkom then cuts my line the 17th for “no payment” I send them proof of payment they “link” to my profile they reactivate my line I get a call the 19th to say they investigating where my payment went to assure me my line won’t be cut again then just after 12am today they cut it again!! I use this line for work and I do not get paid if I do not have internet!! I am disgusted with your service
