Bad Bananas/ Clever Girl Brand Won't Replace Misspelled Name on Wine Glass Internet

I ordered several personalized wine glasses as Christmas Gifts back in November 2016.  One of the glasses came in with a misspelled name (showed up as Debby, not Debbie) even though I had emailed the correct spellings.  I have emailed several requests for a replacement, and 6 months later I am realizing I am not going to get it, even though it is paid for already.  

When I finally received a reply from them it became apparent that they had my order and another persons order mixed up, and they HAD sent a replacement glass - to a different person!  They told me that since they had already sent the replacement to me, there would be no further communication from them, and they were quite nasty about it.  But I dont have my glass!  They copied me on an email from someone else who is angry because her glass said "Debbie" - not "Debby as she had ordered.  so whoever this person is obviously got my glass and I hers.  

But the company will not respond, and I think they have blocked my emails because they will not go thru now.  Nice customer service - ha ha.  but they had no problem keeping my money.  

I wouldnt risk ordering from them- what a waste of my time this has been.
