New Sendle 250g express service WARNING

I have trialing using the new low cost 250g sendle service promoted by ebay for ebay plus sellers.    I have noticed many parcels are picked up but online tracking shows futuile pickup.  I have resorted to taking a photo of the parcel and drivers scanner as proof it was posted.   My customers are jumping up and down thinking I have not posted.  Sendle dos not reply to emails and has zero customer help.   Has anyone else come across these problems?

I would highly recommend you do not use sendle under any circumstances, going by their google ratings ebay should not be partnered up with such a company.
