I received the shipment of the 20 x 10 foot Walk-in Chicken Coop missing five 1815 mm tubes. I notified Aleko and was emailed that the missing parts were being sent via FedEx. I contacted Aleko asking if I could order additional 940 mm tubes to increase the coop height since it shorter than expected per the picture of the coop. I plan on using the coop for my peafowl which need the height. The representative told me they could not order additional parts. This is surprising in hindsight because I received a call after the email from Aleko stating they did not have the missing parts in stock and the parts had to be ordered. I have sent an additional message addressing my request to order an additional 12 x 940 mm tubes via Aleko chat online on June 23rd and have yet to get a response. At this point I am frustrated and at a standstill with a coop that cannot be fully assemble to use. I still hope I am able to order the parts needed to enhance the coop for my intended use. Thank you for your assistance on this matter.
