Poor Service Delivery for Fibre Installation

I have app**** for Home Fibre with MTN on the 25/02/25. I was told that application was approved and the order for the Installation was sent to the Service Provider. 2 days ago after doing a follow up with Supersonic I was that Openserve had an issue with the address but it was sorted and that they will contact me. To date nobody has called and the Installation still has not been done.
