Misleading investment company

I invested an amount of R8000 with them an paid R800 admin fee, the investment was made on the 4th of March 2020 until the 25th March 2020 ( 15 days). On the 25th March I went to them they said they are busy they will make a transfer after hours. It was two days before lock down in south Africa and I had to travel to my province of Mpumalanga ( 1100 km) that day as their branch is in the Northern Cape, they transfered an amount of R9400 In my account and I reinvested R6000 over the phone for 30days which was going to pay me R14000 in 30 days ( from the 25th March 2020 until the 11th May 2020.

But believe me I've been in contact with them they are telling me to come and collect it. And I ask them how cause I'm faraway in lock down I can't travel to provinces. And before that they promised to transfer the money and everything have changed I'm not a happy man.

Please assist in this regard
