Aramex complaint

Aramex collected a package from me on the 5th of July 2018. The package had to be returned to Amazon. I printed the labels received from Amazon and the package and labels were handed over to Aramex with the instruction that the package must be shippef before the end of July. If not shipped by end July Amazon would not accept the return. I asked to be notified if anything else was required for shipment to takr place. Aramex confirmed Amazon woulf be billed fot the return. Three weeks passed and despite two follow up emails from myself to Aramex to ask if all is in order NO FEEDBACK was received from Aramex. When following up on the shipment for the third time in the first week of August I was told my package was never shipped because I never paid a shipment fee and I did not provide Aramex with the correct psperwork. Aramex never communicated this with me during the three weeks that yhey had my package. Now my return period expired and I am suffering a huge loss. When I complained they blamed me snd said I should have ensured that the paperwork was in order. Badly done Aeamex, really poor service deliver. In dact NO SERVICE delivery at all.
