Quick to push the blame

I am honestly disappointed in the service that I received from Net Florest. I bought a personalized gift for my partner on his birthday. When the gift arrived the surname was spelled incorrectly. I called them immediately, I spoke to Quatina. Who organized for the gift to be collected and said I'll receive a voucher. Collection was done and all. She called me tell me I am only receiving half of the money I paid because "THE FAULT WAS ON MY SIDE". To cut the long story short I tried ordering again making sure I dont repeat the same mistake. Then I realized the system only take 10 characters for the surname. I called to enquire and again Quanita told me there was nothing that they can do as the system was made that way and I need to choose something different WOW. So what happens to people with long surnames, they cant order personalized items. Well to my surprise today I received an email with the same voucher number but with the full amount but when I used it yesterday it was half. I am honestly totally dissatisfied and I'll never use them again. The service is bad and they are quick to push the blame.
