Poor Service Delivery

I purchased an online Headboard from Makro on 17th December 2024 Order No. #MAK*** with a delivery date of 30th December 2024. There has been no communication from Makro Online team as to when I will receive my Headboard. I sent an email to them but received an automated message stating that they have many emails that they are working on. When a big Company makes a promise to deliver and it does not deliver, surely ther should be communication from them
