No after sales service

I ordered a pair of Chelsea boots on the 18th of march. They arrived on the 8th of April. When I asked why they were taking so long to be sent I was told there delays in the production. The shoes were too big so I requested a return through the website. I was provided with a waybill and instructions and the next day the shoes were collected to be returned. The arrived back with veldskoen on the 12th of April. In an email exchange with Nic Latouf I asked that all shipment details be sent to me then the new pair were dispatched. His reply "absolutely!. I have had ABSOLUTELY no further correspondence from Veldskoen, my emails, WhatsApp messages ,a facebook message, an instagram message all remain unanswered. All I would like to know is when they will be sending my shoes, that I paid for over a month ago???
