Dear Sir/Madam,
This is regarding detail experience letter which i need as a part of my immigration process.I raised a request for the same in the portal but my people manager(Ravindra.[protected]@in.ibm.com) rejected it saying i did not work on the technologies mentioned, when i called him initially he asked me to call later and when i called him the next day to discuss and clarify things he started ignoring my calls, i tried mailing him couple of times but did not get any response because of which my immigration process is getting delayed...all the responsibilities which i mentioned while raising the request were absolutely related to my experience and the skills which i mentioned are very much relevant...if i did not work on those technologies i want my people manager to educate me on what skills i have been working during my tenure in IBM, even i am interested to know that...for no reason he rejected my request and is not responding to me in anyway...i request IBM hyderabad HR team to intervene and provide me the detailed experience letter failing which i will be left with only one option to proceed legally to get the letter.Thanks
