Refund Issues

We paid for a deposit for camping site and later found out that we are no longer able to travel on the booked dates, we requested Lake Eland to do a refund for us. We found out that they deposited the refund into an incorrect bank, we gave them the correct details on the previous emails. What is upsetting is the time frame it has taken them to give us our refund. On the 03.09.2019 I requested for them to follow up, there is no money since.
