Ola Electric — Helmet size not proper and RC card not provided

I received my Ola S1 scooter at 30th March 2022. At the time of delivery, I tried the helmet and it was not fitting properly. The helmet was of kid's size. I raised the issue then and there with Ola supervisor and she told that she can't do anything and directed to contact support team through mail. I contact them on that day itself from till that time it's more then 3 months and I haven't received and updates till now. I paid extra bucks for the helmet apart from the scooter. The Ola Electric support are also not ready to refund the amount. I asked them to take the helmet and refund the amount because I paid for the helmet separately. But they told once the helmet is delivered they are cannot take it back. Also, it is been more than 3 months till the scooter delivery but I haven't received the RC card till now. After raising complaint multiple times they are unable to provide any solution. I generally takes 15 days for RC card. The order id from my scooter is OET-[protected]-GXX323.
