I have been working with Speechpad for a few years now and my experience with them has been entirely positive. Any issues I've ever encountered with deadlines/time limits, the rare system glitch here or there, or difficulty with files (either being more intensive than anticipated, missing portions of transcription, or format questions) have been addressed fairly and efficiently.
I've never had any problems with receiving payment. On one isolated occasion, a file I submitted somehow was also submitted by someone else... don't ask me how. I was accorded the benefit of the doubt and paid nonetheless. Similarly, on the rare jobs when my own computer problems or other personal issues have necessitated a longer-than-usual period of time in which to complete a file, I'm pleased to say the staff at Speechpad have always worked with me to enable completion of the file.
Many of these critical reviews seem like sour grapes to me. Speechpad requires accuracy and consistency. From what I have seen from a handful of the files I've reviewed, those requirements are often ignored (along with obvious instructions in the Style Guide). If the work's not up to par, obviously that's going to be reflected in a less than pleasant experience. Doing solid work, on the other hand, should result in a strong relationship with Speechpad.
My main advice: communicate. If there is an issue, email the staff at Speechpad. Jill, Krystal, and everyone else I've dealt with have always addressed my issues/problems/concerns/questions honestly and without delay. It's hard for me to believe that many of the situations described here couldn't have been resolved -- or at least improved -- by contacting the company for help and guidance.
