Change account conditions

We ordered a lounge suite from Coricraft Parkview 1st week in January 2015. We app**** for a 6 months interest free account. We only received the furniture the 7th of March 2015.<br> End of January we paid the card protection fee and other fees total R58.00. In February I was phoned and informed that the account is in arrears. I mentioned to the lady that we are still waiting for the furniture. She then said she will note it on the system. Two weeks later another person phoned me and then told that I have to pay the January and February portion, they don't care if the product was delivered or not. I then paid the amount for 2 months.<br> I noticed that the description of the account changed to 6 months budget at a ridiculous interest rate of 22.65%. I spoke to a consultant and he told me that I have to pay interest now every month.<br> On the account I received today is also an entry for a collection letter. I have not received a letter, so how can they charge me for a collection letter.<br> For February I had to phone for a statement, nothing was mailed or posted to my postal address.<br> Can you please change the account back to a 6 months interest free option?<br>
