Package not delivered for 3 months

I have been trying to get a shipment delivered to me. It has shipped before the lockdown from Germany. For about three months, the shipment has been sitting at customs, with any feedback information to me. Tracking ID is: Disclosed I was trying to have two things done: (1) Clear customs, (2) change the shipping address because my office is closed due to Level 3 lockdown. - I have phoned about ten times, both customs and tracking: - Eventually, I was told the customs was cleared, but since than my tracking number does not track online anymore (I've sent the required customs information) - I was in touch thereafter with Leboza via Email about rerouting - It has been two days since, I still cannot track the package online (as if it does not exist anymore), I cannot get any response from Leboza who is supposed to be helping and the call centre is saying that the package has in fact not cleared customs.

What I need to see: - If the waybill number changed, please let me know. I want to be able to track it online; - Has it be been cleared from customs or not now? I am getting misleading information. Note: I've forwarded the customs documentation to DHL; - When will it be delivered; - Has rerouting worked.
