WORST CUSTOMER CARE AND ONLINE SERVICE

I placed an order online and paid for it, a week later I'm told the item is out of stock and they have given me online credit. I phoned in and complained, Someone named Emma was supposed to call me back to give me a voucher that I can use in store to compensate for the loss and inconvenience that was on the 6th of December . Now 8 days later no one has emailed or called me. Tried to get through every single day since then, no one answers the phone and no one replies to emails. This is such pathetic service I am disgusted! Most people have been purchasing for Christmas presents and now they ***** from clients and inconvenience them! I am absolutely appalled. I will never support the online store again!!
