Unhappy Customer

An order was placed with your company on 04.09.2020 morning payment method was a gift voucher , after realizing that order was cancelled on you website and i tried to re-order it said my voucher as no credit available the same day around 13H11 i sent an email for this to be rectified and you rep**** requesting voucher details and i provided you guys with that and since Friday you guys have been quite its Wednesday today with no resolution to my query, this is very unprofessional as a business to treat customers in this manner
