WHERE IS MY ORDER!

Please do not let these people assist you in store with Click and collect. We went to buy a sleeper sofa on 28 Jan. With the long rows at shop and the online special running we decided to buy online. The sales assistant said he should do the order, then we can collect in store and store and do not have to pay delivery to our house. First I saw the email coming through that the order will be sent to the Grove mall, which is nowhere near the Centurion Lifestyle where I bought and paid. Then I was informed after numerous follow ups, that the store assistant mistake cannot be changed Followed up last week on order and it was the Centurion Depot. I cannot collect there, but it is also not being moved to The Grove. Followed up again today and now they first have to send emails WHEN WILL I GET MY ORDER!!! Why can I not just go and collect (ANYWHERE) in Centurion, where I ordered it in the first place.
