Unhappy Customer

My account has been suspended for being arrears and i know i was a month behind whereby i did fulfull my payment and the activate it again. Aal wnet well i got and statement which said im 1600rand in arrears again and then they sent me sms to say im 618rand behind again which was confusing. I then ignored it because i paid my full amount that was in arrears and got the proof of it and the people at telkom informed that everything will go back to normal installments. Telkom deducted abit this month of the actual installment and i left it so and now again they suspended and they tell me im 618rand behind whereby they already deducted. There's no agents that can help you after business hours which is ridiculous insane and bad for business whereby other networks have there 24/7 agents to assist. Now im sitting without data because telkom is using 3rd parties to conduct their business and evens telkom employees said its stupidness. Whats more insane you have to wait a whole week for them to activate your services which is mad. Conclusion.... i paid in full and the problem comes from there 3rd party finance department who doesn't do there job properly and if i go to telkom at the store they cant help me coz they not working with accounts and now i must run around!!!!! I just need clearity on how does it work with telkom and departments and where can i go to sort out this problem...just need immediate assistance and any other networks that i can change to with better data deals as for telkom disappoints me and im so long a customer by them.
