Now that I want a refund his rude. He told me not to call him

On the 1st of February went to maboneng at upon the lens studio to take pictures at the studio of njabulo Sithole and we had an agreement he quoted me R1100 for 55 pictures. We took pictures, we payed.. he was supposed to edit them and I will get the 2day later but that never happened.. He just kept on postponing, he would ignore my calls.. He ended up promising that he will refund me because he can't edit the pictures because they are *******ed.. But till today he hasn't refunded me, he blocked my calls, the photographer is unprofessional.. His name is njabulo Sithole name of the business is upon the lens
