Had a similar experience, case fell apart after a week and the sales person refused to give a refund or replacement. Same issue the sales person wanted cash and did not give a receipt so he did not have to charge tax or claim the sale. This place should investigated for tax fraud. I am also disappointed with the mall management for allowing such a dishonest retailer to operate. This place is a ripoff and their products are garbage. Avoid Cellairis at all cost!!!!
