DISHONEST COMPANY AND NO SERVICE

I have an outstanding query from last year, where I never received my medication and they have till date not come back to me. Confirmed that the address they delivered was incorrect but still haven't refunded me or send medication. On top of this I was forced to pay up to date for outstanding payments, before new medication will be delivered. So I have paid up even while they haven't resolved my query. I have also requested for an updated invoice since over 20 days now,but with no luck. Received an email that they have send my request to their financial department. Today I received my medication but my wife's medication not send. What the he'll is wrong with you people?????
