Delivery delayed

I placed my order on the 21 January and I received one of my items on the 25 January and the rest of my parcel I have not received. I have emailed Incredible Connection three times and I received an email saying someone will be in contact, no one has contacted me. I then received an sms on the 1 February stating my parcel is with the courier company and I will get delivery. I then tracked my parcel and I read that my address problems. When I check online it states that my parcel has been delivered. I then received and sms at 19.46 to say we are unable to deliver your parcel. This is the worst experience I have ever gotten from Incredible Connection and it will be my last order.
