Bad customer service

I have a contract with telkom. I usually pay last day of the month, June I decided to pay on the 27th. On the 16 of July they suspended my service when I call they told me the money it's hanging I must send proof of payments I did. They never helped me. 17 July I called after I sent several emails then the lady said it appears she will send email to open my network. 5 hours later I got email saying I must pay R70. How can I pay R70 when I paid on time? Now they don't want to open my devices they protecting each other
