Vintage Joint - dodge company

I bought a Springbok Jersey from "Vintage Joint". Except for the fact that they did not keep to their indicated delivery times, the jersey I received is way too small even though I ordered a 5XL. I wrote to them an email and a WhatsApp message to tell me how to return it and get refund - no response to date yet. They seem to be very *****, so my suggestion is steer clear of this company at all means, rather go and buy your goods at a sport shop in town where you can fit it and feel the quality. In this case it is sad to say that online shopping failed me dismally.
