Poor service

I upgraded on the 4th of September. 3 weeks later I still did not receive my phone. After 3 times follow up they keep on telling me they don't have stock after the consultant who assisted me with the upgrade assured me they have stock. This morning I was told the courier companies are closed during lock down which is not true as courier companies are working. I've been at Cell C all my life and never had any problems. Always good service but this time I am disappointed. It is almost time for me to pay my upgraded installment and still no phone !!!
