Four Indian electric two-wheeler manufacturers, Ola Electric, Ather Energy, TVS Motor and Hero MotoCorp, who were found billing their charger and proprietary software separately by the government probe, have refunded only about INR 10 crore (USD 1.3 million) out of INR 305.64 crore (USD 41 million) expected from them. The slow refund process was partly attributed to the non-availability of bank account details of customers, according to the companies.
