Maggots in Whiskas Gourmet meat platter 2kg

We bought Whiskas Gourmet meat platter 2kg at n store near us. It had Maggot in and we sent an email to customer care. This happend 25/4/21 it is now 16/5/21 and i have emailed more than once only to hear that they are still investigating. I really feel that we deserve a refund at least, seeing that we spent money on something that was not up to standard?
