Worst service ever, please cancel my contracts!!

I ordered my upgrade on 6 December, and I've had no communication whatsoever regarding delivery. Yesterday I reached out to you on Facebook, you said the courier company couldn't get hold of me, which is a lie, I've had no missed calls or voice messages from any courier company. You also told me I would get feedback today, but nothing. No communication whatsoever. Every month you debit my account exactly on time, but when it comes to my needs, you couldn't care less. Please can you revoke my upgrade request and cancel my contract, so I can go to a service provider that is actually interested in their clients. I also don't understand why the courier company has to phone me - why can't they just deliver???
