FNB poor account migration service

I recently migrated from a Premier Fusion account to a Premier account but I am still being debited on my Premier Fusion account and I cannot access this profile in order to reverse debits. I was **********ly debited by Rain internet service twice in February and March and would like this money reversed since I cannot access the accounts' debits. This is very poor service from FNB and the person who assisted me in the migration.
