Tcs pf transfer issue

Dear Sir, My previous employer has a exempted PF trust head quarter at Mumbai. I am posted at Chennai. I joined this organisation on April 2015 and relived on July 9, 2019. I applied for transfer of EPF accumulation to previous TCS to first source through online transfer, received Annexure K also. Also raised grivance but still now amount not received o Now i moved to first source to another company. I raised online grievance on epfigms portal then I got response from EPF that the amount has been transferred. After that , in response I got hard copy of Annexure K for one PF account with detail of Cheque sent to trust address. I sent the same to my First source. However till date they are insisting that the amount is not credited in trust account. I again raised a online grievance in epfigms portal, then again I got response that amount has been already transferred for both the accounts also telling that "pursue your employer to send application about non receipt of amount. Also I do not know what happened to my EPS transfer. Now I am worried about my money. Since both the offices are not giving any solution how to take up the matter. What are the legal options to get my money in account
