Failed Service and Failure to resolve Ongoing Complaint

I am writing to follow up on my formal complaint submitted on 22 December regarding the prolonged delays, poor service received at a Vodacom store, and the faulty condition in which my phone was returned. In Vodacom private reply I was advised that I will be contacted. To date, I have received no further communication, updates, or indication of progress. This lack of follow-up is extremely disappointing, particularly given the seriousness and duration of the issue. As a reminder, the phone was returned to me without essential system applications, including default apps such as the Google Play Store, rendering the device unusable. This remains unresolved. Extremely disappointing customer service from the branch and now the complaints department.
