Google Ads Payment Specialist Needed

We are looking for an experienced Google Ads payment specialist who can help us resolve persistent Google Ads payment failures.

Current issue:
Google Ads returns error code ending with 07 (commonly OR_FGVEM_07), meaning the transaction/payment is being blocked or declined.

What we already tried:

Around 19 different bank cards/accounts
Multiple banks from different countries
Different payment methods
Different browsers/devices
Billing profile adjustments

Despite all attempts, payments are still failing.

We are specifically looking for:

A freelancer from India experienced with INR manual payment Google Ads accounts
Someone who understands Google Ads billing/risk/payment systems deeply
Preferably experienced with:
Organization-verified Google Ads accounts
INR billing profiles
Manual payment setups
Solving payment suspension/payment decline issues
High-spend or agency accounts

What we need:

Diagnose the real reason behind the failed payments
Help us successfully fund/pay the Google Ads account
Provide a long-term stable solution
Possibly assist with proper billing/account structure if needed

Important:

We are NOT looking for basic Google Ads campaign management
Only apply if you have real experience solving Google Ads payment/billing issues
Please explain similar cases you solved before

We are ready to work long term with the right expert.
