Subscription to "My kitchen" magazine, delivery of 1 magazine since June and still awaiting refund as at 28 September

Subscribed to the "My kitchen" magazine on 20.6.2017. A month later I had still not received the first copy. Eventually arrived after umteen email queries. Then another month passed, and the next magazine was advertised on the Foshini Group My Kitchen face book page and I still hadn't got that one. I asked for a refund. I was told by Highbury Safika Media that they could not do a refund without my credit card details - strange, as I had paid with it. Weeks later I ended up phoning them to give me credit card details - and I am still waiting.
