No customer services

Placed an order on 4 March for a Gazebo for delivery from Home Depot. Received 3 boxes on 14 March and opened to assemble on 16 March only to discover that a box was missing. Reported it on 17 March as the contact centre was closed on 16 March. Was told that they will contact the vendor and get back to me asap. We had high hopes and left the other parts as is on our patio to wait for the other parts to arrive. Home Depot never phoned back and I started phoning them daily as it is raining daily and the parts and boxes we had was getting damaged as well as our patio furniture that we backed out and the reason for buying a gazebo. Not once was I phoned backed as promised by agents that were not allowed to give their names and was never allowed to speak to the same agent or manager. So it started as a daily request to find out where rest of my order is and reporting to Home Depot that the boxes are getting damaged by rain. Received mail on 28 March that the box will arrive on 2 April. I phoned customer services to tell them that it was then to late as we will have no time to set the gazebo and requested a refund. Again no communication and me phoning daily to get money back and scheduling pick-up of boxes that was delivered. As of today 1 April no money back and me having to deal with courier company to pick up stock. We all work and are not home the whole day to wait for a courier company to phone or collect stuff. Home Depot agents are no help and just giving me orders to speak to courier company. Also they will not credit the product until they receive the product back. I will not recommend buying from Home Depot at all. On the same order we ordered a Club Cadet lawnmower and bagger. The bagger box was not in original box and had also missing part. That we ordered directly from Club cadet website as we already have an unresolved case with Home Depot. Would advice people to not buy at Home Depot, but rather buy the same products from Amazon or Vendor directly.
