Gst of gta forward charged for notified person

Hi, we are a startup company, has a GSTIN and fall under notified person category, a Registered GTA gave service to our company and charged 5% under forward charge basis and Final amount after same paid through bank transfer. Should i have to pay RCM on the basic amount seperately?

If the GTA doesn't pay our forward charge to govt, How can i receive the ITC?.. Pls advise
