Elite mobile is dishonest

I got an unsolicited call this morning from someone at elite mobile from *** telling me that my daughter was using excessive data and that for R25 less per month, they could migr me to a package providing more data. I asked how much was used, and was told a lot. I accepted and then checked and her data usage is minimal. I would have been paying R300/month more. I then confirmed with vodacom amd have tried to change the upgrade. Not sure if it's happened. This is completely dishonest amd unacceptable
