I have been asking for a product for the last 4 days and there is NO response from them.I have called them,send mails,messages etc but their response is NIL. Even while buying a product if their attitude is like this then we can imagine their after sales service. When we call them they say that they will come back to you,but they never do that. Chat is saying that their sales will contact me BUT THEY NEVER.I have to literally beg them to ask someone to call. Even after confirming order they do not respond,I have to call them to see if they are processing the order,as there is NO TRACKING system.
Really not professional at all.
