Refund from Vodacom accounts department

<p>before getting my contract with vodacom i was told to pay an amount of 1500 for a " Gap account" Ive been calling them to refund me back the money since well my contract has expired, a month ago when i did my query they told me i would be refunded within 7 working days. ive been calling them several times and all they do is transfer you from one department to another.</p>
