Go to Yell with MTN Yello

Can you please stop spamming me. I have had a contract with you guys for many years, but you are now getting on my nerves. I am receiving all kinds of messages at all hours of the day. Anything from loading data bundles to competitions and promotions. Let me make this clear. I don't want ANY SMS's from you EVER. Don't phone me, I'll phone you. Who's rocket science idea was it to start spamming your clients anyway ? Please unsubscribe me from any and all communication lists.
