It is highly disgusting to note that they are just brokers to look for commission business. I have two experiences. One the extremely good service and the next one to shatter my impression about them. It is no different than a marriage broker.
Once the payment is done they take their commission and leave it between the poor customer, courier fellow and the so called invisible seller.
If anyone from Amazon.in reads it call me or mail me. I have so much of agony to drop on you.
