Reymar freight courrier port elizabeth

So i did a booking the before our nationwide lockdown began.I did an over night courrier this was on the 25th of march 2020.So when we got the headsup to go back to work on in May 2020 i sent an email for the collections department and ask if it possible to offlaod my box.No reply! When i phoned the office they said i must speak to the Floor manager ,wich i did.He then said he will find out where is my box and call me back.Waited a week no responce or what so ever from him.I phoned again the next week,he then said "oky ill find out"and then put me through to someone else.So after try and tracing my box, they said no its ******,during lockdown they broke into one of their depos. Fine and i said no its fine ,whats the way foward.After many emails and phone calls no one can give me straight answers. I then phoned head office wich i spoke to a very friendly lady there.She then helped me.abd suddenly now when i phone her they me she is busy and se said i must phone .... in Pe branch he will help me.its been a while that no one can help me.Bad bad experience with them ,Ive been patient the whole time now,but no one can give me answer whats the way foward will be.i sended my invoice and then got told,the people responsible for the loss wouldnt pay that amount back and they are investigating .
