down loading norton product

dt: 30.6.15  India   

I at 20.08 started down loading my norton internet security product which I had purchased on 29.6.15,  1 year for upto 3 PCs.

Today at 20.08 I started down loading  but internet connection went off I immediately reconnected  but I am stuck up  at 33% down load since time  22.07 to till now  I tried chat help but that also could not be initialized .  Would I require to reprocess down loading  has my time and efforts fromm 20.08 hrs to 21.58 hrs  at 33% down load leve is wasted.  I am  the moment want resumption of down loading process from 33% onward  is it possible. ?
