Am I just unlucky when it comes to domain name transfers?

It really begs the question when two out of three domain name transfers in the last week involved companies sending my clients usernames and passwords to their control panels that just don't work! Having forwarded them to me to double-check it's not like I'm relying on the word of my clients, trustworthy as they are - they just didn't work, period. Time to chill out by going here - Wine Anorak, or here - House of Wines, or here - Steep Hill Wines. Sometimes I just wonder why... some hosting companies "just don't get it". Good night.
