Good morning Linda sorry for the delay in responding to your query.
The most likely cause is the flex has come off the drum inside the vacuum, in which case any motion pulling or winding in will not help.
To resolve the problem, remove the dust bin, unplug the vacuum, then remove the top cover which is secured by 5 philips head screws on the under side.
Once the cover has been removed you will see the flex entering the rear of the vacuum then on to a plastic wheel, from here you need to untangle the cable and guide it back out. All in all it should take you more than 20 minutes to take it apart free the cable, then put the cover back on.
Sorry for the delay in responding please try and rate me now.
