UTTERLY DISSAPOINTED - RETURN

I ordered a pair of high heels, and they broke on the first day. NOT ONLY that, I requested a return and they accepted it. When I got their confirmation email, I responded by saying that my address changed. I called the driver and asked when can I expect the pickup and he RUDELY told me he would pick up my package on Friday at my new address. He called me again the same day when he was two minutes away from my old address. I logged a complaint and Zando ensured me it was solved and a new pickup agent will collect my item at the correct address. AGAIN THEY WENT TO THE WRONG ONE. I logged a complaint again, and they ensured me again this was a mistake. After which there were no attempts to try and collect my item and I kept receiving emails stating that the pickup failed when simply no one even tried. I emailed them again, and another representative logged the complaint and issued a return AGAIN. I thought all was well until I got a call from an agent on their way to the WRONG address again. I am sick and tired of this.
