Failure to pay refund

On 16 July I paid for a premuim ad on AutoTrader, after which I received a phone call stating that there was "something wrong" with the photos that I posted and that my add was rejected. I opted not to upload new photos as I did not have time to take new ones. I was informed by Vogan Jacobs that I will be refunded immediately and that it will reflect within 7 business days (see emailcommunication), which should have been 25 July. A few days after speaking to Vogun, someone else from AutoTrader phoned me again to ask if I am planning to fix my pending add, with no knowledge of a refund. I told them the story again. I have no business chasing after money that you took from me for an add and did not place, promising a refund and failing to pay it back. If the money does not reflect in my account by tomorrow, I will be rightfully launching a complaint with the Consumer Goods and Services Ombud.
