Poor Mediocre Service

I don't often purchase online because of situations like this. I must say that I am extremely frustrated and disappointed in your service and attitude. I bought a pair of talkies online from Sportscene on the 28 Nov 2019 a day before black friday. You sent me notifications for payment and acknowlged and thank me for the payment you received knowing you did not have stock. Later that week without even a call to explain and apologise I received an email telling me you unilaterally cancelled my order after been paid by me and creating an expectation and contract. I accepted this, you advised that a refund would be effected and to date nothing. I've been waiting over 15 days for a refund you said will take up to 5 days. Please attend to in haste I cannot wait until the new year for my refund. You are welcome to request my refund reference.
