Unfortunately it is not currently possible to change the date your instalment payment is taken. You can look in your Member Dashboard for the breakdown of when your payments will be taken.
How do PMG instalments work?
Instalments are an in house payment plan over a set amount of months - usually 5 or 6. Upon each payment your account is allocated a set amount of Home and Flexi points. Promotional and Friend referral points are paid to accounts upon the final instalment.
Please note: Failure to make an instalment will render the membership in arrears and the account disabled. If the arrears are not cleared all points accrued will be cancelled and removed.
