Great value-for-money service comes at the cost of endless spam

When you sign up to become an MTN customer, you are signing up to endless spam. I get at least two SMSs every day. There is an option to opt out, but you have to follow the same USSD prompts 15 times to opt out of every single service. No option to opt out of all services with a single command.

Other than that, I've really received great customer service and good reception when I need it. I'm very happy with the service; if only I could choose to not be spammed upfront, or at the very least opt out of all services with a single command.
