Aweful service from Zando

I received a promo email from zando and decided to purchase a few things. It was not mentioned in the email that the promo was ending at 3pm. I wasn't aware of the cash on delivery option so l added some items in the cart and ran to the bank to deposit some money so l could make the online payment. By the time l tried to do the payment the sale had ended but they took my money. This was on the 18th of April and today is the 20th and the money is not in my account. I phoned and they told me that the payment had been reversed but my question is why they took payment for an invalid order and it's taking more than 48hrs for the reversed payment to reflect in my account. Very dissapointed with their lack of urgency by not clearing the reversal. Things are tough...why assume that l have this money just lying around. Tried to shop in another store and l was so embarrassed when my card had insufficient funds. You are good at sending promotional emails but no communication regarding my payment "reversal". Hope this gets sorted out soon.
