Disappointing After Sale Service

Purchased a Siemens EQ6 automatic coffee machine in November 2020, the unit stopped working in March 2021, less than 6 months old. I handed the unit into Hirsch centurion on the weekend of the 12th and was promised a new unit would be provided by Wednesday 17th (this after the assistant had spoken to the store manager) I followed up telephonically a week later after having heard nothing back and was told I will get feedback Monday morning by Monday afternoon I had no feedback, went in store and again was told I need to wait and can expect a call the next morning before 11am. Till today I have had no further communication. Really disappointed in the after sale service received from Hirsch.
