Abhorrent Customer 'care' from Cielo/Wheco group

With the level of customer care close to zero, one should think twice before buying items online from Cielo. I bought 2 Jorja Contemporary bar chairs and only one was delivered. The waybill also indicates 1 parcel was delivered. Its close to a month now and my complaint has not been resolved. I have queried with the courier company (not liable) and Cielo. Every time I speak to someone from customer care, its as if it a new complaint. Today I called more than 10 times and I was unable to speak to an agent. Additionally no one from customer care calls back to provide feedback. That is what customers need than having to do the chasing as if you are at fault. Also there aren't prompt responses to emails. Customers deserve more than this.
