Builders express East London, bad service with faulty machinery

I recently purchased a Ryobi Mbs 1200 belt sander from Builders Express East London.

The first time I use the machine, the front roller locked up. Assume it is a bearing that collapsed, the machine was brand new so I took it back to the store. The store refused to exchange it as I bought it 3 weekends before, (more than two weeks as per Ryobis exchange policy taped to the counter).

I then agreed to send it in for assessment. In the meantime I had to purchase another machine because the job at hand can't stand

It has now been two weeks and I am yet to receive a status on the machine. I have phoned several times, and almost never get through to the store. I then phoned customer care rather than the store directly and was advised the store would get back to me. This also never happend. When I finally did get through to the store I just got cut off.

I am completely unsatisfied with the service I am receiving from builders, as well as the quality of the Ryobi belt sander.
