Think & Learn / Byju's — Replacement of the wrong product you gave

Address:

I recently ordered a byjus monthly trail pack for std.10th cbse and the invoice no. TNLPAYU066422 and the order date is[protected].
When i got the delivery, the product I got was 10th icse, which means that I ordered for cbse and i got icse . i called the customer care and they just kept arguing with me that cbse and icse are same and it is a foundation and the portions would be there in it. I said them that the portions are not same then also they just kept arguing with me about the same. Are the customer care people illiterate that they cannot even differ between cbse and icse . Then the customer care people said me to talk with my mentor[name: Baba Rohit and phone no.[protected]] .
I called my mentor and explained him everything . He said he will see what he can do. Its been nearly 15 days since i explained him. I called my mentor everyday reminding him about my complain. Once he said that the package is now opened so nothing much can be done. Now if I dont open the package then how will I know about the product I ordered.
Day before yesterday when I called the mentor he said that I should again order another one in cash on delivery and he will return the transaction that I made earlier .
How can I trust your system that you will return the money.It is clearly mentioned in the invoice details that the product I ordered is of 10th cbse. It is not about 1000 rupees, it is about that I am a child of std 10th and you are mentally harassing me rather than immediately replacing my ordered product.
Yesterday when I called my mentor he said me to call customer care again. After this much 15 days of mental harassment, I should call customer care again. Then also I called the customer care and they have already told me to call my mentor and say him to replace my product[a few days earlier] and I said my mentor about this and he has done nothing till now.
Please solve the problem by replacing the product as early as possible as it is affecting my studies.
