Repaying deposits

After vacanting the property I was renting on 1 september. After issues were sorted, myself, the owner and the agent came to a solution and they were to deduct only R250 from my deposit and interest. On Wednesday the 13th I was asked for my bank details so that payment can be processed. Needless to say it has still now at 5pm on the Friday 15th not been done.Apparently, the principle of the branch can only do the refund and she is hardly ever in the office or the gent has missed her. Besides the fact that after asking nicely to keep me updated, there is silence and I do not hear a word. I am the one always calling, messaging or following up but to no avail... I think that is what annoys me the most is the lack of communication. Then the agent gets annoyed because I am bugging her the whole time wanting answers.
