When charging, Fuel surcharge will be 1% or 10rs. (whichever higher) + GST.
And during surcharge waiver, its 1% + GST.
Ex:
400 Fuel will charge you (1% or 10rs. + GST) = 11.8rs
1000 Fuel will charge you (1% or 10rs. + GST) = 11.8rs
and surcharge waiver works as
400 Fuel will give you 1% = 4rs
1000 Fuel will give you 1% = 10rs

The value on charge slip will differ from the credit card statement since the Surcharge & GST is levied by acquiring bank post the transaction. The 1% surcharge waiver (excluding GST) for eligible transactions would reflect separately in the monthly credit card statement.
