My experience using send my bag had been really positive until February 2024, when I sent a suitcase ( made out of rigid plastic, so measurements cannot change that much) from Rome to Madrid. The bag arrived crushed and with one broken wheel, but I didn't complain about it. Little did I know that 2 weeks later, when the suitcase had been unpacked, I would receive a message saying that my bag was bigger than the dimensions I stated. I cannot get my head around how a sturdy suitcase could expand and I'm puzzled that they intend on making me pay 20 extra euro for something I cannot prove, as I unpacked my bag already. Very disappointing.
