Why does the Postal Savings Bank say that there is no financial allocation every month?

Every month, the social security of the Postal Savings Bank says that the lack of financial allocation is due to problems in the integration of the banking system and the social security payment system. The counter-offer time of the bank is 3 working days, and the counter-offer of the social security system may cause information delay. Social security payment time: the social security processing time is 1-20, and the social security bureau transfers the fee from 22 to 30 (the transfer time in non-urban areas is advanced to 10). Every month, the social security fee will be transferred to the system account of the tax bureau, and then transferred to the personal account by the tax bureau, usually before the end of the month. The balance on the personal social security card can be found around the 3rd of the following month. Failure to pay in full means that all the expenses of the pension have not been paid to the local tax account. The reason is that the bank has not transferred, the unit has not paid enough, and the local tax has not included social security fees in social security. Social security payment means that social security is not paid normally for several months for some reason, and then the social security for these months is paid back.
