Why cant I get assistance by walking into a vodacom shop???

I have made a payment toa vodapay wallet on the 13th of March and up until now the vendor says they have not received funds. the vendor is even making it out to be like im a ****mer. I have sent proof of payments to vodacom and asked them to verify that the amount has come in or not (including the vendor) and vodacom has not responded. I walk into a vodacom they say i should call. I call.. there are no options for vodapay wallet. how can i get resolution to this matter. I have been sent from pillar to post. Please can this be resolved!!!!
