MTN Prepaid *****s airtime

MTN prepaid is ****, I have ignored this for too long. Everytime you load airtime they give you subscriptions you don't know about. They always wait for you to load it and send you a message "Thank you for subscribing to GoMoji" etc, you can't even call the call center because all you'll hear is the voice prompt and not giving you an option for a service agent. The best network but *****ing airtime is their business
