MTN can't connect me to their network

Travelled overseas. Always have been able to activate and deactivate sms roaming with ssd commands. Now - after 2 emails (first one 4 days ago) and 3 calls to service center I am being told that they will not be able to register my phone on the local network before Tuesday (4 days from now) - admittedly because of a mistake on their side. Been a client for 6 years, number unchanged, never missed a payment. My question - how to you compensate me for the time I don't have a phone and my time? This is just not acceptable. Would give zero stars if I could.
