WHAT ONLINE SHOP DOES NOT EXCHANGE SIZES!PATHETIC EXCUSES!TERRIBLE CUSTOMER SERVICE ALL ROUND!

I bought a pair of sneakers towards the end of January 2020. I received them 3 February 2020. They are too small. I bought them whilst on special. When i tried to log a return to get a size bigger it didn't give me the option, the only option was a refund or store credit. I phoned Zando querying this and they said they dont do exchanges, the best they can do is refund me. I was shocked to hear that they dont do exchanges - i mean what online clothing store doesnt do exchanges. They said they would refund me, and then i can just buy them again - however the price of them now is double the price. I was not accepting that they dont do exchanges. No where on the returns policy does it state they do not exchange sizes, but only refund. No where does it say before you are about to pay the item that they do not exchange sizes. Fadswa (however you spell it), called me back and proceeded to make their problems mine and told me straight out that i am welcome to go to the ombudsman. WOW fantastic customer service lady!! You should not be in the position you are if thats the way you speak to your customers. I called the ombudsman and they emailed me the link to lodge the complaint. Of course if you go onto Zando's page on facebook you cannot post on their wall. So i commented on their posts along where others have complained. I put the ombudsman link on my post - only to find Zando removed my posts and blocked me from ever commenting on any of there posts. Shooo well aren't you guys feeling guilty or caught out that you have to do that to one of your loyal clients who continuously buy from you. I will not ever buy from you again, the ladies in my office will never buy from you again. WELL DONE ON LOSING HUNDREDS OF CUSTOMERS DUE TO THE TOTAL LACK OF CUSTOMER SERVICE!!
