Sheet Music Plus Customer Service Issues

I am a piano instructor seeking assistance. One of my students is using the book "Performing in Style" by Dennis Alexander for the Certificate of Merit program. The program requires knowing both the piece names and composer names. Unfortunately, the book only categorizes the pieces into Baroque, Classical, Romantic, and Contemporary sections without specifying the composers. I am having trouble identifying the composers for the pieces. Any help would be appreciated.

As a piano teacher, I've tried numerous times to purchase specific piano music for my students on Sheet Music Plus, but I've encountered login issues. Even though I paid $4.99 through PayPal for a spooky easy piano collection, I can't access it for download. Whenever I try to login, I receive conflicting messages about my email address. The Halloween variation of Itsy Bitsy Spider initially caught my interest, but now I can only find a collection with 2 pieces of Halloween music. I really need help resolving my login problems on Sheet Music Plus so I can continue using the site for its variety of options. Thank you. - Kaye A.

Hello, yesterday, I sent an email to the helpdesk regarding my payment made with iDeal for an order at Sheet Music Plus. Although the money was transferred successfully, I have not yet received my sheet music. I urgently need it for rehearsal with my ensemble this weekend. I sent the email yesterday from Lucienne de Valk in the Netherlands at [redacted] In the email, I specified that I ordered two pieces for a brass ensemble. Could you please review my email and assist me in receiving the sheet music promptly? I already have an account with Sheet Music Plus and haven't encountered any issues with my previous orders. I hope you can help me today, and I apologize for the rush. Thank you, Lucienne de Valk
