I purchased a pair of shoes which arrived quickly but were the wrong size. I processed the return according to instructions on the site. The website glitched and didn't open return window nor allow me to add tracking number. Trekkinn advised purchasing replacement shoes separately so as not to delay receiving them due to COVID. $70 to return the shoes. I emailed Trekkinn the tracking number for follow up. Package arrived in customs within 3 weeks but Trekkinn did not follow up until I emailed. Days before any responses or generic responses telling me to just wait. Each time I have followed up I have been fobbed off. Finally asked Australia Post to follow up. They found package had been in customs in Madrid for over 6 weeks and triggered a response from Trekkinn. Apparently Trekkinn sent documents to customs - why were they needed when I followed all instructions for returns provided to me?! Still no reply/update. Months have past with more emails telling me to just wait. Finally asked Aus post to contact them again. Apparently my package was waiting in customs until 7th August when the import was terminated due to lack of follow up from trekkinn. Package was sent back to Australia by ship 22nd October. I have now have to wait for the return and will have a pair of shoes I can't use, paid $70 for them to travel the world and sit in Spain for 6 months and wasted the price of my shoes. All because Trekkinn has provided incorrect return information and has shoddy service. DO NOT RECOMMEND UNLESS YOU WANT TOP THROW AWAY YOUR MONEY!
