Entire document did not convert and data from different cells showed up in one cell?

I just purchased a 1-year subscription with Adobe to convert PDF files to MS Word or Excel. First, after an hour or more of waiting, the document was still "uploading". Then I went through my emails and responded to a couple from Adobe, and tried to convert a document from PDF to MS EXCEL through the internet. What I got was an Excel document that was missing all the column headings, and which jammed a lot of data from different cells into single, individual cells - but even that was not consistent, with data from other cells showing up in other cells! I think I wasted my money!
