Excellent service from Mattress Warehouse Durban! Mboh and Thabani were absolutely amazing throughout the whole process
Excellent service from Mattress Warehouse Durban! Mboh and Thabani were absolutely amazing throughout the whole process. They provided great feedback and suggestions, were always ready to help, and made choosing the right bed a really easy experience. A special mention also goes to the delivery and installation team. They had the difficult task of getting the bed up to a top floor, which was not easy at all, but they handled it professionally and with smiles throughout the entire process. From the store to the delivery and installation, the service was exceptional. Thank you to Mboh, Thabani, and the whole team for making the experience so smooth and pleasant. Highly recommended! ud83dudc4f
