After we had put together the entire unit and were inserting the drawers, we could not get the first drawer in. We studied what could be the problem for like 3 hours !  Until we realised that the inside of the metal rails were simply not sliding. Attaching picture to show where the defect is. So, here we are with a fully assembled item, with a big gaping hole where we cannot insert the drawer. Have tried to file claim online for the last 24 hours, but each time I submit, there is a problem with Wayfair's server and am asked to please try again. Please try again ?  I have tried 15 times to no avail!  So then decided to call Wayfair customer service today.  On hold for 30 minutes, no one picked up, so finally hung up.  What is this ? Really bad service that's what it is.  Wayfair, please contact me asap to resolve this problem, thank you ,
