No response to email enquiries

I sent an email enquiry regarding bring ice skates onto a local flight to the Mango’s enquiries email on 2 December 2019 as I could not get through to the general enquiries department via phone call. I have not yet received a response. I have sent follow up emails to no avail. The airline endeavours to respond within 48 hours of receipt of the email in line with their operating times. I have just received an email indicating that their inbox is full thus my latest email was not received. Perhaps this is a reflection of the lack of attention to email enquiries.
