People who will go to hell😆. We were forced to sign the document retroactively only in this case we were made an intercom!!! I had to pay for 6 months of a broken intercom. The grief came, the master twisted the wires that were interrupted, now the intercom works every other time and it's faster for us to make it ourselves! Within 3 years, you can recalculate for those days when the intercom did not work, but for this you need to write a statement, I think to surprise them after 2 years, let them finally work!
