Struggling to get my R700 refund

I ordered a pair of tackies and as per their Ts & Cs I wanted to return them so I didnt collect them from Takealot. On 14th April I received confirmation that the order had been cancelled and to allow up to 10 days for a refund. To date no refund has been received and my queries about my R700 refund go unanswered. Very dissatisfied with this.
