Waiting 7 weeks for a warranty

On the 22nd of July (today exactly 7 weeks ago) I returned 2 items for warranty. One was a memory kit and the other a tone and probe. When I followed up on the 21st of August I was told the memory was still at the supplier and the tone and probe was not yet sent in (it was forgotten). Since then I have phoned every week and received the same reply: It is at the supplier and we'll get back to you. Now I worked at Matrix Warehouse years back and one of my jobs was warranties so I do understand that there are hiccups from time to time, but I also know that it is of critical importance to keep the customer up to date. Finally.... it's already 7 weeks... surely at this point some compromise has to be made. 2-3 weeks is the norm, not 7 (and counting).
