parcel force forged my signature!!

Pound

Keep in mind that if the driver did steal the item they have to sneak the item off the van before they get back to the depot as they can hardly be seen leaving with a parcel under one arm.

If it's a regular occurrence and the driver drops it off somewhere it will quickly arouse the suspicion of neighbours if the same van and driver is seen taking parcels into the same house. Even if they did manage to not arouse suspicion it will be picked up by the delivery company if the same driver keeps losing parcels. A driver could theoretically steal items but it would be very hard to do it more than very occasionally.

So, again, I think it's much more likely that it's been delivered to the wrong address and fraudulently accepted.
