Unprofessional service after complaint

On 17 July I placed an order for an arrangement to be delivered to our office. The roses were not fresh as the outer petals had a "burnt" look. On 18 July I emailed NetFlorist to advise them that we were not satisfied with what was delivered. I received a reply and a request to forward photos, which I did on the same day. By 20 July I had still not received a reply, so I emailed them again and was again asked for photos, which I again sent, and on 24 July I followed up again to request feedback. As of 31 July, I have not received any feedback and find the level of service completely unprofessional. Seems I'm wasting my time requesting a reason as to why the roses were not fresh!
