MTN - DATA *******

I've been a MTN prepaid client for the last 7years, recently my number got deregistered and I needed to RICA (only received notice of this on the day it was disconnected). I immediately go to a MTN shop to RICA, just to find another sms that in 21 days I have to RICA AGAIN!!! When the number was disconnected i lost 7GB day time and 20GB night time data, I called the call centre three times and all three times they ensured me it will be restored. When I called again today to follow up - the consultant tells me it will not be restored. This is not the first time data has just been revoked.
