Worst refund policy ever!

I made a purchase from Takealot last week. It all seemed great until I was told I couldn't get one of the items I had ordered. I requested that one of the call agents find out if they can get the parcel from their suppliers. During the conversation the agent told me he can't make a promise before he even attempted to assist and if ever they could get the parcel it would take me up to 6 months to receive the parcel. I was unhappy about the response I got and the attitude that it didn't matter that they had advertised something they don't have, but regardless I asked him to call me before the end of the day (yesterday). Till tonight I have not received the call back regarding my order being fulfilled or a possible refund. I sent another email during the day requesting a call back and that was ignored. I don't know how I'm supposed to know what happens next if no one cares to contact me regarding this disappointing experience. Nothing is as frustrating as dealing with *********** people that have no regard for specific requests made by customers. This is my last attempt at getting a call back! Please can I get someone to call me back and sort out my full refund. I've already rejected the other 2 parcels since the order was incomplete.
