Missing Data package

I purchased two bundles last for my modem last week ***. I purchased a 1.8gb which is valid for 2 or 3days and I purchased a 9.7gb which is valid for 30 days. Both these packages disappeared after 3 days and don't show up any active bundles under that number in my Telkom mobile app profile. I called 180 for assistance and I was told the packages expired. How can a 30 day 9.7gb expire after 3days. ????? The customer service was unable to assist me and simply dropped the call after not having a solution for me. I proceeded today to the Telkom branch in Umgeni Rd Durban. I spoke to this person Yonela Zintle which was pretty clueless and offered no solution but uttered the same line that the package expired. I asked for the usage logs and was refused. Now do I have to open a case at SAPS for the alleged theft of my data package. I have tried everything in my power to get answers to no avail.
