UPDATE: I've revised my earlier assessment of Royal Crown after being pleasantly surprised by their recent follow-up service. Although my initial experience with Royal Crown (and its aftermath) left something to be desired, they recently contacted me in an effort to address a number of concerns.
This time around, the company sent a new assessor/estimator, Eni, who was tremendously professional, kind, courteous, and thorough in both his explanation of various potential problem areas and the repairs he conducted on our downspout. Both he and Rachel, the acting office manager, were lovely and thoughtful, and followed up to ensure that the work was complete and to make sure I wasn't left with remaining questions or concerns.
Although I was dismayed by our previous miscommunications and by aspects of the work that was done, I have to say that Royal Crown has made a tremendous effort to rectify the situation, and I would recommend them based on the quality of their repairs and their recent customer service.
