Lannies board and hardware bloemfontein

I have been using Lannies as a supplier for years now and as common there were mistakes here and there, (wrong panels being edged etc.). I placed an order which I receive with many mistakes (wrong measurements, panels incorrectly edged) of which I send some of them back on 02/11, corrections that can be fixed in less than an hour. It toke 4 weeks to receive the panels back after many visits where I was promised I will receive then the next day and countless calls only to find that not all the panels were return. It's been week now and still waiting, just receiving promises and excuses
