Dear Sir/Madam,

I have sent sim registration forms from sweden to india on 26 September 2020. it has been not delivered untill today. Tracking from sweden shows item has been reached to dehli (tracking number UK[protected]SE). but it doesn't show any update after this. we have enquired at local (Nagpur) post offices and they are also unable to answer. Please look into it and revert as soon as posssible.
