Stop giving me wrong information and contact me about correct steps for vodacom to refund me

Why is vodacom giving me wrong information and failing to just refund me first they told me that I must go to my bank to do a chargeback which is impossible now they told me that I must go to my bank to fill a dispute form in order for them to process my refund so that my bank can send this dispute form to their absa forensics team but dispute form doesn't work that way according to my bank and dispute form expires after 30 days and 3 months have already passed can vodacom just refund and stop giving wrong information to take to my bank I feel like vodacom is giving me all this information so that I run out of time and forget about getting my money back do they right thing I can't just loose that much money jerr what's wrong with your eshop and finance department let them do they work once ..
