UNAUTHORIZED DEBITS

I WAS CONTCATED BY RAIN AND SOLD A 5G PACKAGE, THE SIM AND ROUTER WAS DELIVERED TO MY HOUSE THE NEXT DAY, AFTER TWO WEEKS OF STRUGGLING TO CONNECT THE DEVICE AND CALLING RAIN WHO GAVE ME INCORRECT INFORMATION, A GENTLEMAN FINALLY ASSISTED TO ME SAY THERE IS NO COVEREGE IN MY AREA FOR 5G AND THIS PACKAGE SHOULD HAVE NOT BEEN SOLD TO ME. THE SERVICE WAS THEN CANCELED AND THEY SAID THEY WILL MAKE ARRANGEMENTS TO PICK UP THE ROUTER AND REFUND MY DEBIT ORDER BECAUSE I DID NOT USE THEIR SERVICE. RAIN HAS AGAIN DEBITED ME FOR NOTHING AND I HAVE BEEN TRYING TO CONTACT THEN AGAIN AND NOBODY CAN ASSIST ME.
