Chaise parsons en coton Julia

I placed an order for four of these chairs on June 3. I received them on June 16 and put them together the same day; that's 13 days from order to delivery. On the fourth chair I discovered that two of the bolts that join the seat back with the chair seat didn't align with the holes to screw them into. I contacted Wayfair and was told I could return the chair, and a replacement would be shipped. I requested that the replacement be shipped right away; I didn't want to have to wait until the return was processed for the replacement to be on its way. My return arrived at its destination on June 24. That's only one week after it was received at my home, and that included 2 or 3 days for me to get it repacked and arrange pickup. Today I received the replacement chair after waiting 3 weeks to the day after I notified Wayfair of the problem and was assured my replacement would be on its way quickly. Why did it take 3 weeks to give me a replacement but only 13 days to deliver my initial order? Sounds to me like Wayfair didn't do what they promised they would do. They didn't ship my replacement right way; they waited until the replacement was refunded and THEN they shipped the fourth chair. I don't think that's a fair policy when the item in the original order was defective! In addition to everything else, the replacement chair I received today was missing an assembly part, so now we have TWO defective deliveries. My husband made two trips to hardware stores to replace the parts; I'm not waiting another 3 weeks for another chair. So, I have three problems with this order: 1) The first delivery had a chair with poor quality workmanship. 2) The second delivery has a missing assembly part 3) Wayfair took 3 weeks to send my replacement after promising a quick turnover
