Personalised Online wedding anniversary disaster

NetFlorist doesn't make occasions special, they ruin it completely. O ordered a nice personalised gift for my wife. All is well and I pay for the order and the system confirms this will be delivered on the 5th of August 2020.

During the couse of yesterday I get an email saying: "We deeply regret to inform you that one of the items you had ordered online is currently unavailable: Personalised Purple Gown . We apologize that we could not notify you before you placed your order. We understand the time and thought one puts in to find the right gift. We sincerely apologize and deeply regret the inconvenience we have cause. We would like to offer you a voucher for the order item value which may be used on a future purchase alternatively we would be able to refund your order amount. We really do hope we can make up for our mishap in some way or another. We very much appreciate your business and hope that you will remain a valued customer. Kindly advise if the above offer for a voucher is acceptable and we will send it to you as soon as possible, alternatively you can advise how you would like to proceed. Your urgent response will be highly appreciated."

I have opted for an immediate refund. Got no feedback and now all their agents are currently busy. Our anniversary is tomorrow. You still have my money and I can't even make a plan to get my wife a new gift now. Thanks NetFlorist. Despite me not using you for a few years because I ahd a similar event with you for my wifes bday you yet again ***** up on a different occasion. This is the last support you will ever receive from me. I'm logging a complaint with the ombuds against you.
