TCS — Onboarding issue

Hi

I accept my offer letter from TCS in 1 February 2023, My last working day in previous organisation was 17 April 2023 . My TCS joining date is 3 may 2023 I went for onboarding my name not in the list i called recruiter he said due to BGV we postponed to may 10 2023 again i went that time also they said my joing date postponed to 17 may 2023

17 th may I went recruiter said u joining date postponed to July 3 2023 because this quarter recruitment is finished.

After two months my fourth joining date came on 3 th July 2023 but on july 1 i got one mail from tcs due to internal approval we postponed joining date to 5 th july . On 4 july first time I got joining welcome mail from tcs to joining. On 5 th july 2023 my onboarding not happened due to date is mismatch in Application form onboarding
team said u need to contact your recruiter to correct it after correct the date we onboarding you I called the recruiter and mail to recruiter to correct the date but no response my next joing date is changed in portal 10 july 2023 I went for onboarding
On 10 th july 2023 but onboarding team said still your date is not changed by recruiter first correct it and then come for onboarding till that even we changed your onboarding date in the ibegin portal do not come for onboarding day directly said to me . I called recruiter no response . I went to meet recruiter manager regarding my onboarding issue . She sent mail to recruiter to take action on it then recruiter called me and said we tried to changed your date from our end but we can't change from our side u called to previous company change the date in experience letter then only we can move forward. Actually My previous company my last working date is printed wrongly 2 days difference instead of 6th April 2019 they printed 8th April 2019 . So i called to my previous company I asked change the date quickly they give me new experience letter with correct date i called to my recruiter as u said I changed the correct date in my experience letter but
this time recruiter said even u changed also we can't onboarding you this time ur onboarding postponed to October month i[censored] want to look for another opportunities try next time tcs.

I don't know what to do .
I have already resigned my previous company from may 3 month without job and salary
I will face huge financial loss due to this and having lots off financial liabilities.

How TCS as global brand can do such things . On the basis of the TCS offer I have not look for the other opportunities.

I am expecting positive response from TCS.
