Disappointed by shake off summer and the service

I have been a loyal customer of vodacom for many years. They have recently started their shake for summer competition whereby you earn vodabucks by recharging your airtime, buy bundles or pay your bill in advance. This is now the third time I am facing this problem. The first time I paid my bill in advance, I recieved no vodabucks until I eventually logged a complaint a couple days after where a technician stated I can only receive that vodabucks the next month as the people reconciling have to check what date it was paid. Bare in mind they took out two payments for that month. By then my puzzles which only needed 1 piece more to be completed, expired. I then did another challenge around the second of December where I paid R500 in airtime for bundles and never received my vodabucks until 4 days later where I again had to complain and it was manually put on within the day! This week I did 3 other challenges, they sent through vodabucks immediately for the airtime I spent and 1 goal however nothing for the other two goals. I proceeded to phone vodacom once again as the Facebook site which previously helped gave no help at all. Always saying uninstall and reinstall the app. I was put through a consultant who stated it takes a 72 hour turn around time for this to happen. I asked to speak to a manager in charge to which he said hold on, I waited on line for 10 minutes before my call was transferred to an automated rate our service call. I honestly feel like this whole shake off summer is a **** as I have numerous puzzles missing one more piece however it expires today and I got no help from vodacom. How can the same situations be address differently all the time. And now I spent so much time on doing this only for my puzzles to expire.
