Errors when trying to migrate content from wordpress.com to .org

I have just updated my www.ads-software.com to the latest version.

I previously had a web developer – who unfortunately did not finish this job – so I am left to sort it.

I have a .com site (krystalscanlon.wordpress.com) and now I have a .org one (krystalscanlon.co.uk)

I’m waiting on a new designer to complete the theme for me – as the current one was loaded by my former developer and not what I originally asked for.

In the meantime, the migration is causing problems:

– lots of content/posts is missing: on my .com version I have approx 189 posts and on the .org there’s only just over 100 posts – I don’t know how to rectify this.

– the current content which has been moved over includes images, text, image slideshows, contact form, image grids, etc.

– on the .org site, some of the posts appear really messed up” the images all overlap each other and the text – causing it all to be visually impaired and completely unreadable – how can I fix this?

I am at the point I am questioning should I just delete everything and start again?! Or delete all contents and start again?!

I understand a lot of developers want all the full cost of migration up front, but my now concern is, I paid my former developer upfront, and this is the mess I am left with. I’m concerned about handing over the full 100% cost upfront because I want to make sure the work gets done, and if these issues arise, then they will fix them – something my former developer refused to do.

Also, is it best to get the correct theme up first and THEN migrate, or should I do the migration while I am waiting?

I have the plugin: All-in-one WP Migration

Thanks!
