Unsatisfactory service

I have been trying to get assistance from Vodacom the whole morning, without any success: I mistakenly recharged my Wi-Fi number ( ********** ) with R150.00 this morning, instead of recharging my normal number ( ********** ). I have tried all I could, phoning in, chatting, emails, to avail. When I tried to transfer the money, their system (My Vodacom) is denying the transaction.
