A little over a year ago I bought an apartment, said apartment included a storage room.
This storage room, Solvia did not give me keys, what's more, Solvia gave my storage room to a tenant who had been rented for a while ... I have been claiming the cost of the unlocking for a year and everything is glue ... What if the bill has to go in the name of solvia when I have been the one who has paid for the removal, that if it is not those data ... Really, incredible mismanagement and how unpresentable they are.
