No delivery - no response from KLL when enquire

After working with KLL Distributors for 3 months this is the second incident we had with them. First time we ordered stock without delivery they informed us after we had to enquire that they didn't have any of the stock we ordered that week. <br> Second time: We ordered stock for our business on the 16th of July from KLL Distributors (Port Elizabeth). After the second day that they were schedules to deliver and still no stock received we started enquiring about our order. We talked to the distribution Manager (Kurt) over the phone (22 July) he never phoned us back. We phoned multiple times to speak to Zulpha Stellenboom and send various e-mail as well without any response on what went wrong or informing us when we can expect delivery. Calls were made and voice mail's left for the senior manager Dave Brenner, he never phoned us back. Final we had to phone KLL Cape Town to give us his e-mail address so that we could put the complaint in writing to him. Still no response from the Senior Manager. <br> At previous employment I worked with KLL Cape Town and never had the smallest of complaint about them. But the Port Elizabeth branch takes the cake!!! Not even responding on a no delivery!!
