Calling in for refunds, when you inform us through email already? Returning refunds as vouchers instead of eft as received!

Dear Mr Price why do you feel the need to email me and state that some of my products are out of stock and will not be in my parcel when I collect or have them delivered to me, but then say I need to phone in and have you people process the refund, what is the point of the email, if you know you will not be placing the product in my order, why must I call to remind you that, "Hey remember that email on your system, the one on your screen you sitting front of? Yeah, I need to remind you that my product is not here." I see no point in this waste of time for the customer, process the refund before shipping off the product. Another thing, I paid you guys through eft, why was I refunded via voucher? What makes you feel that the products I ordered can somehow be replaced with your other non-similar products? Just like when we purchase with our Mr Price account and ask for a refund, you do not return cash but refund it back into our Mr Price accounts, I think the same decency should apply when we purchase through eft, return our money the way it was received, do not send me vouchers, you did not have my product so I have no use in buying something I initially did not want!
