Poor internet connection

Greetings, I have phoning customer service to complain about the network connection, I receive no assistance, ever since I started using this service the connection is a mess, and I cannot pay for that, I even switch and buy data from Telkom just because this unlimited network is not working. Yesterday I got a message saying I didn't pay, everyone at home was telling me not to pay because since I've opened the Hotspot for everyone the network just doesn't work. Yesterday I was given connection until the 18th of January to make payment, I took is but wake up this morning, boom the network is disconnected. Please help, I can't pay for poor connection that switches completely off most of the time.
