Hi everyone,

Few of you probably know me from my earlier post and i keep checking everyday here and its good to hear people giving out advice
Right about me,
I applied for a royal mail job on 7th december 2014
Got an interview on 10th february 2015
Now on 5th may i had an email from HR that we are delighted to confirm that you have passed the interview and we are currently waiting for confirmation with regards to Mail Sorter vacancies at Heathrow Worldwide Distribution Centre / International Logistics Centre.
When we have received confirmation, we will contact you again to discuss your application further"

Now ever since i have been waiting and i have tried to contact HR via email and after couple of day i get the same response that they still waiting for the confirmation and it happend twice already now i am confused as the vacancy stated that it will be starting early 2015 and i really dont know what to do?! should i just hang on and having said that i have not been working all this time thaught i will start now now now but its taking long
What should i do?
