Visa Transaction simulation program in C++ - c++

Question

I am doing a data structure project and it is important to write my own template linked list class implementation ,it is required that:
Each visa account can do a transaction using the visa card and the transaction is recorded in his account with date and amount of money due.
My steps :
make a list of accounts in the system.
each account has it's list of cards, as it is required issuing another visa card with different number but to the same account.
make for each visa a list of transactions.
My problem:
that the transactions made by the card not saved in the list of transactions that is defined in the card class.. you can check the function settrans to see how I implemented it . how can I fix that ?
2.The balance "The sum of all transactions" is not updated, which I need it later to let the user pay.
NOTE : The main is not completed and there is another data I need to do another functions not completed yet so no problem if you found excess paramters.
and I didn't put pre or post conditions yet.

Edited part:
1. changed all the data in node class to pointer to data
2.
card * list<T>::getcard(int i, string p)
{
node <T> * temp = head;
card* c;
while (temp != nullptr)
{
if (temp->data.getid() == i && temp->data.getpassword() == p)
{
c = temp;
return &c;
}
temp = temp->next;
}
return &c;
}
solved part is that there is a transaction list with different transactions saved in it but the account list and card list have the problem:
if I add john to the accounts and then joe
it will have two accounts with the name joe.
and same problem with cards list
