Untrustworthy Company that lacks customer service

This is by far the worse online company I have ever encountered. You cannot call them as there is no contact number. You can send a million emails with queries/complaints, yet this company never bothers to respond to any. Whats worse is that you do not get the cashback as promised and when you send a query, it goes unanswered. Cashbag owes me tons of cashback. I would like people to know that this company cannot be trusted!!!
