Hi
A great mistake has been happened from the office of your DMP by sending your medical to London instead of New Delhi. As your file is being processed at CHC New Delhi, your medical will be sent there sooner or later.
At this situation what I suggest you to do is :
1) please inform CHC New Delhi that your medical report was erroneously sent to London office by your DMP. Provide the details from DMP office such as courier tracking number, name of DMP, his address and the date of medical examination.
2) Contact Immigration Section, CHC London and inform them what has happened. You should provide them also your Immigration file number, visa processing office, name, date of birth, nationality, medical date, DMP name with address and the courier tracking number. However, it would not be so easy as we think to get a possible response within a short period.
No mistake was made, for the past year, DMPs are instructed to send the medical result to their Regional Medical Centre rather to the one serving the visa office where the application is. The Visa office then retrieves the results electronically.
