Luno terrible system and service control

Since May/June this year, I have been trying to make contact with LUNO. I even have ticket numbers generated by their system but to date no call nor email. It's been more than three weeks with my account blocked, I cannot be able to do any further. They asked me for proof of payments and I immediately sent them the documents. But their response has been extremely long. Later on they decide to close my account. They took so long to reverse the money back to my bank account. Now they are holding my money and I am not able to continue with my business. There is no one to contact only support chat. I am extremely frustrated and I feel this is very unprofessional. If you want to disable an account for a security concern, the response takes ages.
