Decjuba is at the centre of a controversial postal campaign, after speaking out against the research methods of a church group.
Baptist World Aid has launched a postcard campaign against the womenswear retailer.
It follows a decision by Decjuba to speak out against the organisation over its Ethical Fashion Report.
After scoring an ''F" grade in the report, Decjuba joined a chorus of retailers questioning Baptist World Aid's research methods.
Now Baptist World Aid has issued a call to consumers to send Decjuba postcards blasting its practices.
Consumers can order the postcards through a dedicated micro-site, by filling out their name, address and church affiliation.
Baptist World Aid blasted the retailer for choosing not to disclose its supplier network.
