Sterkinekor refunds

Sterkinekor has been promising our money for almost 2 weeks now, a lot of payments went of twice and no seats and no money first they promised for end game after 72 hours and then it was this Thursday and this Friday still nothing, I love sterkinekor but this is just unacceptable I go there at least 3 times a months but after this customer service I would have to reconsider, I rep**** via email more than 10 times I called customer service and Facebook messaged them and then I was told I am not replying so my case will be closed in 24hours? But it's acceptable to take two weeks for our refunds?.
