Terrible Service

Absolutely terrible!!!! My experience has been terrible since the day I've made an order for a new contract. Every time you speak to them it's a different story. They debited me very quick, yet told me my device would take 5 -7 working days. This was said my multiple people and today I was told 7-14 days. That is a breach of contract. I'm fed up I don't know what to believe, there is no management to speak to and every agent gives a different story, what do I believe?
