Bio metric if lost in post from solicitor

[amjadleeds]

Hi everyone ,

Bio metric letter received on 10th December and solicitor posted to me on 12th of December , still on 15th of December I havn't received it. Today solicitor on holiday so cant confirm until Monday either she post me special delivery or normal recorded , letter issue date was 6th of December as letter indicate I can registered until 21st of December. In case of lost in post what I have to do otherwise they invalidate application.
I have scanned copy which my solicitor send to me before posting me. Please any advice , really stress , I need your prayers , if I will get on Monday original will be great , photo copy don't accept by post office.

Please give me advice what I have to do. your response will be highly appreciated.

Anjum
