Can I cancel my payment method in Self Pick-up option?

No, you cannot change your payment method once order is placed. If you have selected credit card mode as your payment method and the payment facility via debit/credit card is unavailable at the designated Collection Point for any reason whatsoever, the relevant distributor retains the right to cancel the order. If you want to change your payment method, you must cancel your order and place a fresh order selecting your preferred method of payment.
