Bad service from Cielo Customer Service centre

We purchased a corner couch at one of the Cielo stores. The service there was good. The problem became when they delivered a couch with two different shades/colours. We logged a case with customer service, to come collect the couch and to deliver the correct couch. It has been 4 days now since we have been waiting for cielo customer service to do something about this matter. I am stuck with 2 couches that are not the same. And the lady by the name of Phelisa keeps telling me she is sending an email to management. She has been sending an email for 2 days now. Now we will be in a situation where the couches get dirty and they will not want them. And I have reported this matter with high priority. But this customer service people do not seem to care.
