Bad after sales service at Adendorff

In January I purchased machinery wort 10k sales service was excellent. 6days later tye orbital sander which I had purchased stopped working. I took it in to adendorff store in alberton where I purchased it and booked it in for repairs which was on 22 January, I received a msg that the machine was sent to technician in johannesburg. I have been to them now 4 times to find out what the progress is an today the 15 February I was told it is with technician and my work is starting to be effected. I was told by AB the guy who assisted or thinks he assisted that I am not the only customer that has items.to be repaired. So he called the so called technical side to escalate my request. I hope this can be resolved or they could just issue me a new machine. It's easy to take your money but after sales services are non existent. Highly upset and irate.
