5 GST on Rent A Cab

We are a body corporate. we are paying RCM on rent a cab service on which service provider does not charge any GST in his bill

Those rent a cab service provider charge 5% GST , we are not paying any RCM GST.

But recently we heard that those service provider charging 5% GST in his bill, these services are also liable to pay RCM.

Is this information is correct. If yes , which notification or circular.

Please guide in this regard.
