Apologies for not attending your call and importantly, our previous information to Khun Thidarat in regard to the certification for Form SPS.1-10.
We noted (from you) that evidence of transaction for contribution of social security funds made through the bank does not need to be certified by the SSO officer. Therefore, a set of Form SPS.1-10 for June 2016 and its receipt will suffice for visa purpose.
Thank you for sharing the updated information.
