***********/irritating/Stupidity/Unreliable

I have purchased a restonic mattress sometimes last year at house and home in Witbank highveld mall, and within a year the bad was damaged due to poor quality and obviously restonic claiming quality of which they cannot prove. i laid a complain last year December however it was only processed in January, in February the shop received the bed but for some reasons they were not able to deliver it and claimed they don't have a driver who can deliver, \what a lame excuse". Later i was told the bad had defect and therefore need to be sent back to restonic and as a result a new one was ordered. The mattress has arrived at the shop and it has been two weeks and still haven't received it and the same excuse \"" we don't have a driver\"". I have spoken to the branch manager and couple of staff but nothing has been done. my question is how competent a manager must be"
