Netwerk24

Apparently a montly payment for the R109p/m price did not go off in May 2019. So this month they took double the amount. No warning. I took out another offer of R170p/m for a friend of mine as a gift. Sudenly that prenium increased to R270p/m. Contacted them and apparently it is a machine/banking loading issue. Now I am in credit with them but the thing that bugs me is that I signed for R170p/m and not the R270p/m. How can Netwerk24 just take money from my account without my concent.
