CELL NO PORTED WITHOUT MY CONSENT TWICE

I CALLED THE MTN PORTING DEPARTMENT ON 04 12 2018 TO ASK WHY MY NUMBER WAS PORTED FROM CELL C WITHOUT MY PERMISSION. THEY COULD NOT TELL ME AND REVERSED THE PORTING. NUMBER WAS PORTED BACK TO CELL C IN AN HOUR. THEN LAST NIGHT IT WAS PORTED AGAIN TO MTN WITHOUT MY PERMISSION. MY CELLPHONE BANKING HAD BEEN HACKED AND SOMEONE HAD BEEN DATA. II CHANGE ALL MY DETAILS WITH THE BANK AND NOW THE PERSON WHO PORTED MY CELL NO HAS DEACTIVATED MY CARD. PLEASE CAN YOU STOP PORTING MY NUMBER WITHOUT MY CONSENT AND CANCEL THIS NUMBER WITH MTN AND REFUND ALL TEH MONEY THEY HAVE TAKEN OUT MY ACCOUNT. PLEASE CONTACT ME TO GET THE CELL NO THEY HAVE BEEN PORTING
