Once the money is transfered, the cust service rep will never contact you since he/she has got his/her comission already... BEWARE!
the only good fact is that you get WHITE MONEY at a decent rate.
MAKE SURE to send the money on a friday/monday morning IST - MAX! since every thursday morning the price SLASHES down if the price is high the week before., ... CROOKS!
you will notice that the US $ rate is usually 25-35paise less than the RBI rate on their website, which is normal. out of the 6times that I hv sent money (i think a lot of ppl sent money on those days) ... the RATE was between 60-70 paise less than the RBI rate. so try to send money when it is least expected by others.
All said n done, you will get the best remittance rate that is also non-taxable. But suggestion would be to use ICICI although it is 2-4paise less, cuz u will get impeccable svc and attention.
goodluck with your remittance.
