It's difficult to pronounce, so I usually go by my preferred name.
(They have my full name from my e-mail and credit card)
I'm most upset that there was no opportunity to resolve this minor confusion amicably, and what really got me the most is that there was no attempt at an apology, considering the e-mail I got clearly stated that service would resume "once steps are taken to remedy the situation"
I was very polite to them, but everyone I talked to at the company was telling me that it was my fault.
I've never left an encounter with a company feeling more frustrated.
