Hai..i ordered a pair of globalite shoes on shopclues.com on 13/02/2016and prepaid the amount of RS.310 on the same day as there was no cash on delivery option avaliable. and i have cancelled it the next day for some reasons. then i requested for the refund .it was intiated on 17/02/2016. and was told that it would be credited by 7-15 days. bt still today i.e 9/03/2016 i havent received no amount in my sbi account . i have checked at atm bt no amt. is credited. i hv called the customer care people and they have given me a 23 digit refund reference number.
now i want to know how would this number be useful to get back my money.
