Extremely poor service

I’ve received extremely bad service from Cielo. I purchased my furniture online, on the 1st of May to be exact. On the 26th of May I received an email saying that orders will be delivered with a tracking number and courier company name ITT that was the last communication I received from Cielo. It wil be a week now and I still haven’t received my stuff. I have contacted their call center numerous times, and no one is able is able to assist or tell me when I’m supposed to get my furniture!!! Courier number, doesn’t go through or calls are being dropped. One consultant said she would get back to me and she didn’t! One consultant said she would escalate it and send me an email, I am still waiting for that email! This is very bad service from Cielo, the call center agents are useless and they make empty promises just to get you off the line. This is my hard earned money now I'm chasing my delivery and no one cares
