MTN fails to activate BIS service on my phone

I have a complaint to lodge with regards to my Blackberry BIS. I was to reload R59 BIS which I did to reactivate my BIS. The MTN service menu said I had a reoccuring BIS for a month. This happened this morning at 00:00 am. The transaction was obviously not processed after it confirmed that it had been and the BIS was never activated and I did not know this and continued to use my phone as if it had been activated. This caused me to use up all of the R60 airtime that I had loaded on yesterday. I contacted MTN customer care and they told me that they saw the R60 airtime recharge but told me that the BIS transaction was never processed. This is not the service that I would expect from my service provider and I am deeply frustrated as R60 is a lot of money to me and now I am left unable to use my Blackberry because of the an error in the MTN service.
