Do you have a reference number when you call the hotline Contact Us again regarding the refund request? If yes, call the hotline and ask why it was not processed to clear things up. Since you concern is account specific the community does not have access to this information.
It really takes time to have a refund processed more for control purposes rather than budget purposes. The Globe business centers or even offices are NOT allowed to disburse checks or cash unless it has the proper clearances and documentation from a higher authority which is subjected to checks and balances and reverification.
It would have been easier if no money or check is involved and require only a debit/credit from one Globe account to another Globe account.
Just to give you an idea, it took my around 6 months for a rival telco to process my overpayment when I terminated an account with them. AS long as you have a reference number with a specific GLOBE BUSINESS OFFICE (not a Globe premium store being run and managed by a separate company) , you may have to follow this up from time to time. They usually fill out a slip for refund requests of which they give you a copy for reference. Try to obtain that if possible and jsut deal with that Business office for this specific transaction.
