Lack of accountability

I have been having issues with Telkom for about 3 months now. I have been on this platform and they called but nothing changed. I changed banking details and requested a change of debit order date in November 2015. They told me to make a manual payment because they don't effect changes within the same month. I made the manual payment but a day after they debited my account and I reversed it because I had other debit orders waiting to go out. In December they didn't debit my account and when I inquired they told me that it was because the debit bounced the previous month forgetting that it was their fault coz they made me pay manually and still debited my account. I agreed to pay manually and was told that in January all the changes would be effected (debit on the new date). The new date came and passed and I calld to find out. Everything is in order in the system but they are not debiting my account. Two inquiries have been opened but almost three weeks later no one has called me back with an update. They are even ignoring inquiries on Twitter. No one seems to know who should be helping in this case. Telkom needs to get its act together in customer care.
