Rak Ceramics India — cheated by providing poor quality tiles

Cheated by providing poor quality tiles. We purchased high price tile of rak company and once it's laid in floor different color shade for each tile. Complaint given to rak, they came took pictures and told will update soon. It's been more than a month now no update and when followed up there telling to contact the retailer and we cannot do anything... Such a poor service and cheating without any guilt.
