Bad customer service/lack of knowledge

December they never deducted on the dates I agreed on which is the 31st.i got sms on the 15Jan saying my sim card is blocked coz I didn't pay,I made a payment on my phone.now I have arrears of R520 I dispute that coz it was not my problem they didn't deduct money on the date agreed on.i got an email saying they apologize my name will be cleared from debt collectors.on the 31st of Jan they deducted R318.when I called them they say it for Dec,how so coz I've already paid.now my sim card is blocked again I was told I owe R5 Yesterday I made a payment of R10.Still my sim card is blocked Apparently the payment hasn't show on their system. When I made another call this morning I was told they deducted for Jan and Feb???with whose permission to deduct for Feb??money is taken but my sim card still blocked. I have an online interview today I've been calling with no luck of help, been told different stories. No 1 knows exactly what is happening on my account I will never ever recommend telkom to anyone coz this also happened to my colleague aswell. I'm very disappointed by the service
