Number still inactive

I cancelled my prepaid contract prematurely in the beginning of January. Monday they decided to switch off my number due to it needing to be \migrated\" to prepaid. Told me it will be activated on Tuesday morning. Phoned Tuesday afternoon. Spoke to 3 different people to hear system is down \"please try again in the morning\". Phoned this morning (Wednesday) to be transferred to 4 different departments because no one works with the issue in hand just to finally get cut off."
