charged pensioner R250 just to help him install two apps

My father, who is 75 years old and has been a loyal vodacom customer for decades, didn't know how to install an app onto his phone, he went into a vodacom store and was charged R250 to install two apps, which anyone knows, is just done via the Play store, free, and takes a few minutes... What VILE business practice to rip a pensioner off and charge SO much for something so simple and which the staff there could have just told him how to do rather than do it themselves. Honestly this is beyond appalling and now my 6TH BAD review on Hello Peter about Vodacom and their service and customer care / help just keeps getting worse. VODACOM, please tell me how you justify charging an old man who needed help R250 to install two apps, which should have taken 2 minutes? Really disgusting.
