Disgusting service

Absolutely disgusted by service of DHL South Africa, I have sent a parcel to Russia and have paid R700, parcel hasnt been delivered as apparently you are not allowed to send a T shirt and chocolate to Russia ( I have never been told that something like this might be a problem), so now parcel is coming back after it has reached the final destination, it has never been delivered (this is what for I have paid 50 dollars for ) and now they are saying its my problem, how is it my problem??????No one from DHL bothered to let me know , so you havent done the job, but took my money????What joke is it????And as cherry on top for sending my friends their tshirt in order to get that parcel back I will have to pay custom fees, my question what type of idiots are employed by DHL who dont check what they send and only realise it when it reached the destination already????? wb#***
