Deducting on my account but my mobile router is suspended.

Iam very disappointed with Telkom , I have contract with them since last year, but this year they suspended my mobile router. When I went to the store in Gateway to find out why the router is suspended it because I missed one installment when I ask them why they never deducted they couldn't give a good reason and they told me that I have to pay R523. 40 just for one installment missed that are penalties. Yet my installment is only R107 a month. Then I paid that R524 via Absa on the 13 September. On the 15 September they deducted R738 from my bank account, I was so frustrated went pass the store in Mutual building west Street I could get help. I had to reverse my money. Then on the 23 September they deducted again R214 went to gateway store they put me through call centre but still they say the money does not reflect on their system but after 48 hours it will be open .But even today it still on suspension. I am Gatvol of Telkom they very good to take my money but not opening my router. So today I went to the store it still not reflecting on their system they told me to wait for 14 working days. Please assist Peter I'm tired.
