I want help and Vodocom did not try anything. I try everything from my SIDE

Ref no. ME-NDEBIOO1 and 1- *** For more than 6 week s was in communication with Vodacom due to my data disappearing at +/- 10gig daily. I've done everything possible via Vodacom to fix this. I've gone to Vodacom shop and phoned Vodacom 4 time(both) I've done everything from my side even resetting my PC. Took both my PC and laptop to IT specialist. they found nothing wrong. For the last 6 week a 124 GB disappeared. Spoke to IT guy of Vodacom - done everything he told me to do. He loaded me with 10gig. I used 200mb. Switch off my PC. that same night 9.8 gig gone. Received sms 11h45 - data gone. Now speaking to their IT specialist with their help - zero help - my opinion poor IT help - Poor Vodacom help - zero on contract - to check hacking or what ever - something is wrong - VODACOM DID NOTHING TO HELP ME - 124GB GONE - I WANT IT BACK OR CANCELL TO CONTRACT WIT NO FUTHER PAYMENT.
