IDP IELTS — Lack of Service and Irresponsible attitude

Address:

FLAT NO G-2, C-P APARTMENT, OPP FUN-4-ALL

I have taken an IELTS exam with Goa Center on 21st August 2021. on 19th August, I resent my corrected passport with change in name and passport no. Despite repeated requests on Email, and calls to service number, I have not received any feedback nor any clarification.The registration at the exam center too was done with the new passport details.
I was issued a Ticket no : [protected]. Till date there is no respose, except for only the change in passport name.
i have got to submit the same to my agent and i am desperately looking for a solution.
I regret i have reached a situation where i am frustrated with the service and I regret i had to attend the exam with IDP.
