Any news on this matter?

I have been in La Cumbre, Córdoba some 3 weeks ago, where I live half of the time besides Germany and could only withdrwaw 320,- pesos a time, but many times/day with my German Maestro card.
Either from a Banco Nación (Link) or a Banco Provincia de Córdoba (Banelco).

I had talked to people from Banelco (they had no clue..) and Link in BA, latter told me that this limit was imposed in Argentina by Cirrus as of April 1st.
First 300,- pesos, than risen to 320,-.
It is a mess as my wife and kids living there normally withdraws 2 times 2.500,- pesos/month (which is our daily limit on our Germany bank of 500,- EUR at a cost of 5,- EUR/withdrawal) and now has to withdraw about 16 times/month, costing 16x5,- EUR!

As of what I was told by MasterCard in the US and Germany, Maestro does not belong to them any longer (?).

My Bank in Germany had no clue about this, is checking since about 3 weeks, but showed signs of being willing to reduce the fees.
