Worst airline to date - unprofessional and no communication

One of the worst and most unprofessional airlines in operation at the moment. We had booked flights from SA to Germany via Dubai leaving on 3 December 2021, these were cancelled with no further feedback from the airline and no way of contacting them for a response. Emirates say the tickets are valid for 24 months , so we re-booked for 16.1. 2022. Once again the flight was cancelled on the 14th with no further explanation or date ss to when flights would resume. We have been trying to get to Europe for business and Emirates through their unprofessional conduct and lack of response or explanation has cost us a lot in terms of credibility, time lost and money. This is my third bad experience with them- NEVER again
