Total and utter confusion at Rochester!

We purchased a bedroom suite at Rochester. All went well up until we made the payment and then had to wait for the delivery which we were told 24- 48 hours max. When we reached out we were told that due to black Friday they were a little behind on processing ( the payment was done as an immediate transaction so reflected the very next day) another few days waiting. Then we received a sms stating that our order would e delivered on the next Sunday. I figured there was an error as not many companies deliver on Sundays. We called the number provided on the sms for questions or to make a date change, and it was confirmed - they deliver on weekends till 7pm, drivers will call an hour ahead of delivery to confirm. We waited at home the whole of Sunday and nothing. In the afternoon we called the number again and were assured it was on the way as it had left the warehouse that morning. Nothing came through. Monday we spent the whole day calling the number on the sms with no one picking up, we called the store and asked for help. They could pretty much not tell us anything as it is not them but a delivery company who manages it, so sorry for us. The sales agent who helped us tried to help but had very little success. With many more calls between us and the store the entire day as now no one knew where the goods even were. All they knew was that they were picked up on Sunday but the driver could not be reached and they did not know where anything was and had no way of tracing anything. In the evening we took a chance and called the delivery centre again, this time they picked up only to tell us - no they do not deliver on weekends, no they cannot help us, we must call Rochester help centre as they have nothing to do with deliveries ( keep in mind this is the number provided on the sms we received) and they dont send out sms's so cannot help. All these calls according to the message on the line are recorded. Monday evening around 6:30 we get a call from someone stating he is delivering be there soon. Then at 7 we get another call, someone different also delivering. At 8:30 we get a delivery however it is one item the rest of the suite is missing and they don't know anything about it. While we are dealing this another call from the first guy now telling me he no longer can deliver today. We try and understand if he has the rest of the furniture but he can understand and ends up hanging up on us. We call back various times with no answer. Today at 6am the next day I get a call that they will deliver in an hour. I have now received all the items. What an absolute nightmare. How is something like this even possible in todays times. You have a partnership with a company to deliver your goods yet the right hand does not know what the left is doing, no one can be reached or traced, there is no control and not one person to provide a clear answer. Absolutely unacceptable. It is the very basics of service. No follow up, no apology, absolutely nothing. How are you in business?????
