On 3 september I payed for 4 pieces of ICs INFINEON SAB-C515A-LN on aliexpress (the first time I buy something on aliexperess).
I'm tracking parcel since more than one month...:shipment number RN062453655CN

After long time,on 6 OCTOBER I saw that parcel was in Beijing and I hoped it was (finally) all ok.
BUT NOW,SINCE 9 OCTOBER, IT RETURNED AGAIN in Tianjin (where it was stopped in the past month).
Is there some logic in this going ahead and back in China ?

WHY PARCEL RETURNED BACK in Taijin instead going ahead ?

Please can someone contact directly China postal service ? I don't know how I can do otherwise : I found just this forum to know something.

Please someone can tell me if this behaviour is usual and is usual to wait for so long time (more than a month) or if there is some PRECISE problem with this parcel?

I need to know if still I can trust to buy other items by aliexpress or if I have to avoid this service in the future.
