MobiMoney complaint

I've been on the line today trying to find out why a mobimoney that was sent to me, is not accessible. The first 5 agents all told me the same story, the funds are pending, but i receive mobi money from my sister in law every month. This month, I'm having this issue. The last agent went on lunch while trying to resolve the issue, but one hour later still called back with no answer as to why my funds are available. Everyone can see the amount on their system, but its not in my mobimoney account. I spent R70 buying airtime to call Nedbank, but my issue is will apparently be only resolved on Monday. I'm very disappointed with the service and that a query of such a nature cannot be promptly resolved
