Online Banking Error

On the 23rd of January I paid my dependencies as usual using the FNB online banking facility to my surprise on the 06th of January I receive a call from home telling me that the DSTV is OFF. I immediately logon to check what happened, I noticed that the reference FNB used was for my levies account, what happened? I drove to the nearest FNB branch Mall@Reds to query my findings; the branch consultant called the online banking department and the online banking consultant told me I entered the incorrect reference so the only thing he can do for me is to forward my problem to the technical department so I must send him the screen shots and sort this problem with DSTV myself. I was very frustrated from what he have said to me, I never updated any of the dependencies references especially the ones I've been paying them for long time without any issues, assuming I made the mistake with out investigation what went wrong is very disturbing. The track record clearly shows I've been paying the same account for some time now this never happened, and all my transactions to the account were done online via mobile. Now I've to call DSTV for your system errors, I'm angry!
