Could not read the character input properly in my IF ELSE statement in C

Question

I'm new in C, hence, I am not sure where did I do wrong in the code. Could anyone help me out? I have tried compiling and running it. It shows perfectly until my second scanf, I've tried entering Y and N. Both will bring me to the below else condition.[This is one of the outcomes when I enter Y][1] Anyways is there a better way to code this program?

int main ()
{
    float totalexp;
    char paymentmethod, eligible, purchasepnp, purchaseadd;
    int stamp=0;
    
    do 
    {
        printf("Enter your total expenses  >>> ");
        scanf( "%f",&totalexp);
        printf("\n Payment using any of the below method?  \n - AEON Member Plus Visa Card \n - AEON Credit Card \n - AEON Wallet \n (Y/N) \n");
        scanf("% c", &paymentmethod);   //Either Y or N, it'll just print both else {}
        
        if (paymentmethod=='N')
            {
                stamp = totalexp / 30;
                printf("You have gotten yourself %d stamps", stamp);
                
                if (stamp>=20)
                {
                    eligible = '1';
                }           
            }
            
            
        else if (paymentmethod=='Y')
            {
                stamp = (totalexp / 30)*3 ;
                printf("You have gotten yourself %d stamps", stamp);
                
                if (stamp>=15)
                {
                    eligible = '1';
                }
            }
        
        else
            {
                printf("\n Sorry, that is not an answer.");
            }
        
        
            if (eligible == '1')
                {
                    printf("You are eligible in the P&P Tupperware products Redemptions!!");
                    printf("There are: \n (A)- Cherio Quad (1 Litre) \n   %d stamps + RM10.90\n");
                    printf(" (B)- Large Square Round (2 Litre) \n   %d stamps + RM18.90\n",stamp);
                    printf(" (C)- Reheatable Divided Lunch Box (1 Litre) \n   %d stamps + RM33.90\n");
                    printf("Please choose A/B/C to make your purchase and T to terminate this purchase.\n");
                    scanf("% c", &purchasepnp);
                    if (purchasepnp=='A')
                        {
                            printf("Thank you for the purchase, \nTotal RM10.90, \n20 Stamps will be deducted.\n");
                        }
                    
                    else if (purchasepnp=='B')
                        {
                            printf("Thank you for the purchase,\nTotal RM18.90, \n20 Stamps will be deducted.\n");
                        }
                        
                    else if (purchasepnp=='C')
                        {
                            printf("Thank you for the purchase,\nTotal RM33.90, \n20 Stamps will be deducted.\n");
                        }
                    
                    stamp -= 20;
                    printf("Your current stamps is: %d", stamp);
                    printf("Do you want to purchase more? (Y/N), or terminate this program (T)");
                    scanf("% c", &purchaseadd);
                }
            
            else 
                {
                    printf("You have insufficient stamps. \n Do you want to purchase more? (Y/N), or terminate this program (T) \n");
                    scanf("% c", &purchaseadd);
                } 
            
            fflush (stdin);
        
    }
    while (purchaseadd=='Y'||purchaseadd=='y');
    
    return 0;
 } ```
