12 month old query escalated into 14 month old query

Anybody else out there with their problems simply being ignored by Vodacom? A sum of more then R5000 was irregularly deducted via debitorder from my account during a 12 month period, every month a new incorrect amount on top of an incorrect monthly payment, for devices I never purchased from Vodacom. See history).This is my 5th review/complaint on Helopeter since the beginning of January this year, and NOBODY from Vodacom has contacted me to sort out the dispute. (I sent them numerous emails, with a fully typed out explanation of the problem as well). I am a pensioner of 70 years old, and really do not know what else to do - Donald du Preez.
