Undelivered orders

I am very disappointed with rosewholesale customer service, I bought two items online and I was provided with tracking numbers however the shipping company (TNT) doesn't recognise the below tracking numbers and my percels were not delivered. It's over 30days heading towards two months .

Tracking number :RU ********** 70NL :RU ********** 38NL

the first order was placed on the 2nd April 2018. The second order was on the 6th of April 2018.. Please advise accordingly or refund me with full amount that I paid
