Sim cancelled

After having had my number and SIM card for a several years, the service was cut to the sim. This is despite it being in a phone that was active and funds available. Additionally, no notice was given and subsequent efforts to resolve the issue has been met with poor service from Vodacom staff, Keegan. I visited the store on 02/04/2024 and was advised I would be contacted within 24hrs. I sent a follow up on 09/04/2024 with no response. A further follow on 16/04/2024 was met with a response with no rectification or explanations. I responded immediately (16/04/2024) and as of 23/04/2024 I am yet to receive a response.
