Byju's — Refund not processed

I have registered my kids TANISHI ARYA in BYJU (Think & Learn Pvt Ltd) and Registration number is TNL[protected], which head office is in Bangalore. They are doing scam with a big charges and not listening student after getting payment. They have committed to refund full amount, if we dont like services within 15 days. The course fee was Rs. 47000 and I asked for discount, Mr Ayyaz and Pulkit Gupta was ready for Rs. 40000 and said Grade 2 and Grade 3 Material we will give you and written on documents and Grade one we will apply through internal Department and I have authority to Give you Grade one study Material. I had paid Rs. 40000 on 8 March, 2021 and we received study Materials fo Grade 2 on 14th March, 2021. After that no one called us for anything to our kids guidance, We called so many times to customer care [protected] for Mentor and also to Sales Executive (Pulkit-  [protected]. But no solution. I asked for refund before finishing trial period, then no response. In this Scam case Mr. Ayyaz Shaikh has a big role (ayyaz.[protected]@byjus.com) I called regular and sent mail regular. Then they called us after a lot of harassment. Ms. Mahima Saini committed for some points, which I am attaching mail conversation and replied on mail something else. I asked for those points, then she never replied. Again facing same issues, ignore and ignore. Today I called again and they confirm for cancelation and sent mail. In mail they mention send back all materials to them. I asked them, who will bare courier charges and if any damage, then who will be responsible, then no reply. They never said or its not mention in Terms & Conditions that if you dont like our services then you need to send all study materials by your side and all responsibility will be Student's parent side. Now they are not ready to pick the Study materials and I am sure that if we send materials to them, then 100% they will damage the products and will claim from us. My concerns is they should pick themselves and process refund immediate. In summary I can say they are not ready for refund our hard earning money and its big Scam in our country, which is playing with our Kids future. From the 1st day they are cheating with us . Specially Mr. Ayyad Shaikh, Mr, Pulkit Gupta, Ms. Mahima Saini, Please take necessary action against these kind of educational Institute, who are playing with our kids future.
