Infosys offer Letter

After clearing the HR round, I have negotiated the offer, then HR said that, it will be subjected to approval and I will get a call from Infosys for the same for justification. But, unfortunately I didn't got the call/offer from Infosys, shall I wait or loose the hope

Interview happened 28th June Call expected 1-2nd July No response from the HR or talent acquisition after multiple email

Anyone please help
