Rude call center agent and delayed delivery

I have been waiting for my parcel from this company , which has been sitting with them since the 22nd of December . No one bothered to update me with the delay , when i finally managed to get hold of the customer service agent by the name of Henrietta, she took down my detail and gave me sob story about the company struggling to get hold of me then she just cut the call, I then called back but she did not answer my call 2 times .
