You're running into a common local variable problem: https://docs.appian.com/suite/help/20.4/Local_Variables.html#using-local-variables-in-the-definition-of-refreshing-variables

Basically, your expression rule is querying the data once and then during each refresh on your interface,
Appian isn't requerying the data it's just getting the cached value. If you wrap local!results in a!refreshVariable() and set refreshAlways to true, then the value will refresh in your interface.

a!localVariables(
  local!results:
a!queryEntity(
  entity: cons!AS_DataStore_Account_Pointer,
  query: a!query(
    logicalExpression: a!queryLogicalExpression(
      operator: "AND",
      filters: {
        a!queryFilter(
          field: "name",
          operator: "=",
          value: ri!user
        )
      },
      ignoreFiltersWithEmptyValues: true
    ),
    pagingInfo: a!pagingInfo(
      startIndex: 1,
      batchSize: 50
    )
  ),
  fetchTotalCount: false
).data,
cast(
  typeof('type!{urn:appian:as}AS_User_Account'()),local!results
)
)

the values update, but only after I refresh the browser

In the interface designer, you should be able to see the value of variables after each page evaluation. Also, can you share the code inside AS_Get_Account ?

local!user: a!refreshVariable(value: rule!AS_Get_Account(loggedInUser()), refreshOnVarChange: local!addedcredit),

still doesn't update

It looks like you actually want to wrap local!user in a refreshVariable. Just using a!localVariables does not make a variable a refreshVariable. Similar to the example above, wrap local!user in a!refreshVariable and have local!user refresh on the change local!addedCredit.

Should I have used a process model instead of a a!writetodatabase?

a!localVariables(
  local!addedCredit,
  local!balanceValue: a!refreshVariable(
    value: "" /*Put your balance calculation here*/,
    refreshOnVarChange: local!addedCredit
  ),
  /*
  ...
  ...
  ...
  .
   Your other code..
  */
  
)

I do not see that you have used refresh variable anywhere in your code. You can do it as attached code.
