Ignore all my emails for reimbur*****t of payment

Dear Vodacom,

I have experienced horrible service. I have paid a double payment 3 weeks ago and I now need the money to be reimbursed. I immediately called a service agent who was quite helpful and he said I should just send POP to the POP email address. I'm not sure if it is an unmanned email address but I have now sent 8 emails with no reply. I even started copying customer service but still no reply. I feel that this is horrible customer service. They are easy to call if you have an outstanding payment. But when you are owed money, there seems to be no service at all.

I can't wait for my contract to end so I can go to another provided.

They have left me no choice but to lodge my complaint here. If I could give a negative 2 for service I would.
