Grahgoods retail

i ordered 1 phone with gst invoice to the respected company address in the February 28th….

but the company person said… still… he didn’t take the input tax return… for that purchase… the seller may cancel the invoice … after .. the product is received to the customer….

this happens mostly in online purchase….he said..

so, now what can we do… either complaint to the Flipkart… about this seller… 

or any other way to resolve this issue..
