Totally Crushed Parcel

I am extremely unhappy with the service received from Aramex!!! I sent a parcel on the 28th of October 2019 in an excellent condition. My customer received her parcel yesterday, the 29th of October 2019, only to find out that one of the packets inside, got crushed completely. I even wrote under the "Special instructions" on their waybill - "Fragile", but I guess to them that means absolutely nothing!! After contacting Aramex this morning and complaining about the situation, they contacted us back only to say that they can not find anything wrong on their side and that they can not do anything about it. This is totally unacceptable as I make use of Aramex very often. I wil from now on not make use of them AT ALL & I will go as far as telling everyone I know, not to make use of their extremely poor service!!!
