Contract data sim going to waste!

Yellow, please assist. My area has lost coverage as a result I do not have connection at all. I have been staying at this address for over 19 years and have always used MTN and never had a problem, hence I took out a data sim card on contract knowing that I don't have a problem with MTN. However, since last week I haven't had any coverage on 2 of my MTN sim cards, now my concern is that I have paid for data and sadly I cant use the data that I have through contract. I have already spend R200 in this week just to buy data on the other network sim card. It is really taking me out of budget as I already have a data sim which I can not use. I have contacted MTN to make them aware (*** ) and they told me that they dont know how long it will take to fix the issue but its a big inconvenience . So what about the data I have on my Sim card and also having to constantly buy data on another network sim just to be connected whereas I am already paying for data with you.

Please help as I feel I might as well cancel the MTN contract and get myself a sim card with Vodacom as I am currently using a Voda sim and I have no problem with the connection.
