Difficulty in submitting email request for help with Smart Switch

Jeez, Samsung. Do you deliberately make it difficult to get help via email? I'm in https://contactus.samsung.com/customer/contactus/formmail/mail/MailQuestionProduct.jsp?SITE_ID=58#none to submit my issue and can't. I want help with Smart Switch which I can no longer access (I have a screen shot of a pop-up giving reason: "The procedure entry point (...technical detail...) could not be located in the dynamic link library" - which i can send you). Your email requires my mobile model # and other detail. I don't find my model # in any drop down list. Its an SM-A305F/DS which Ive inserted in a field which appears to be the correct one but you seem to require that I select from a list: Catch 22! what else might be wrong in my inputs? Will only know once i get past the model number issue. This refers also to the Captcha characters which are somewhat illegible so how many times might I have to attempt these also?
