Not receiving double deals as paying for

Once again Telkom disappoints! I signed up for the double your data deal(30 gb + 30 gb daytime 30 gb + 30 gb night surfer wifi) and now again (second month in a row) I have received a message stating I am in out of bundle rates.According to Telkom my bundle data is used up. I am supposed to have 60 gb daytime not 30 gb!!! Now i have to call Telkom mobile for the 7 th time and ask them to change my data bundle settings in their system again!!! I am getting fed up!
