No assistance at all!!!

Vodacom was paid twice in error.<br> Proof of payment was sent on 26/02/2015, confirmation was received on 02/03/2015 that refund will be processed and today I receive an sms today that they did not received the proof of payment and I will need to wait another 10-15 working days.<br> Proof of payment was sent to [Email Removed] I received a delivery notification and still they need a fax today before they will look at a refund???<br> This is the worst ever, if you own them money they phone you 10 times every day, but if they own you, you can forget to get any assistance.
