Faulty product sent & now still waiting for a solution!

Bought a product from them and when I tried to use it was faulty. Issued the Return reports below and asked them to send a better quality product when they collect the defected one but they just ignored. No way to call them & they do not call.me. Until today I do not have the replacement items! Return report# -RRN-2615-af98 -RRN-2b46-81b9
