No channels on my streaming services!!!!

I paid my monthly subscription as usual however for some reason, my channels have disappeared. I have channel 100 and 3 other channels. I tried to reach out to consultants and I was told that my email is not linked to an active account. I find it strange because I always use my email address to access MyDStvApp and make payments. It has never given me a problem. Your consultants failed to assist. Still stuck with 4 channels on my streaming services.
