NO SUPPORT FROM RAIN

I HAD RAIN 4G WHICH I CANCELLED AND WENT OVER TO 5G BUT ON 1 AUGUST 2023 THEY DEDUCTED BOTH PAYMENTS 4AND 5G AND NO REFUND ON THE 4G AND THIS MONTH THEY TRIED TO DEDUCT THE FULL AMOUNT AGAIN. I SEND NUMEROUS EMAILS AND LOGGED FOR SUPPORT AND RECEIVED NO CALL OR SERVICE SO FAR FROM THEM. SUPORT AND E-MAILS FROM 3 AUGUST UP UNTILL NOW TO SORT THIS ISSUE AND THEY DO NOT ANSWER CALLS.
