Milestone Credit Cards complaint: Unprofessional customer service

I called milestone because the name on my card was spelled wrong when I called to correct the name the customer service lady made it like I’m the one who made the miistake when the customer service lady who attended me was laughing and talking with someone else while serving me it’s unprofessional disrespectful if this person worked for me I would’ve fired there ass cuz if she did with me I’m sure it was done with other customers again I’m not the one who spelled my name wrong on top of it they would take a payment but I can’t buy anything cuz my name doesn’t match the card how am I responsible for someone else mistake horrible customer service once I pay this card milestone or any other company connected to milestone will not get my money this is the worst experience ever and I have a few cards Milestone has the worst customer service I ever delt with they have these Filipinos answering the phone and their spelling the names the way they pronounce things how dumb is that
