While paying dp of ₹10, 540 for activa 4g from my credit card today cashier deducted ₹10, 750 (Including there processing fee of 2%) and proveded with recept of ₹10, 540 when i asked why is there discrepancy in the amount deducted from me and received by you he said its there processing fee which the charge from customers and provide no recept for it.
When i insisted for a recept of ₹10, 750 chshier rudely said provide cash otherwise this is what they do and can not help it.

When making it an issue and after lots of argument with manager and accountant they provided me with another recept of difference amount that is ₹210.
