poor service

I have been a customer of Home choice since 2006 and my goods were always been delivered at my house, in June I placed an order and to my surprise I got an sms on the 12th of July 2017saying that my order is ready for collection at the Post Office, I then phoned homechoice to enquire and was told that there is nothing they can do and will have to go and collect at the post office, I asked which post office was that and was told the one near to me, I told the lady that was assisting me to tell me exactly which one as I have 3 post offices near she wouldn't say I then had to go to all three to trace my order, I then placed another on the beginning of August and was assisted by the lady call Sadika, I asked her to make sure before I can make an order that the goods will be delivered at my house she said they will be again I got an sms to go and collect at the post office, I phoned and was assisted by Khaya who gave me a ref no ********** 50 and said will call me back and never did, after two days I phoned again which was Thursday the 4th of August and Spoke to Unathi and he also gave me another ref: ********** 5 and said he will call me back on Thursday or Friday and never did, today the 18th I phoned home choice and spoke to Noxolo only now she is telling me that because of the area I am staying at they could not deliver, why was I not told before, and as their customer why was there any form of communication stating that going forward my orders will only be delivered at the post office. am soooo disappointed
