I've used Sendle for 2 months with no problems.

Until last week.

Parcel was picked up OK. Next day they attempted but were not successful in delivering the parcel. To a metro school. The big noisy building with lots of little people running around. Looks like their driver couldnt find it.  5 days and 6 log ins at depots later, and my parcel still hasn't been returned or delivered.  Customer has cancelled order.  No phone number to contact Sendle, only emails that they don't respond to.

Sendle is great  - convenient and cheap - when all works well.  But absolutely dreadful trying to get ANY customer support if something goes wrong.  

Be wary.
