Builders your staff and management don't have a clue how to give customers the service they deserve.

We have a small exclusive landscaping business. I purchased roundup concentrate for R370 from builders warehouse garden route mall. To my surprise the stuff did nothing to the ****s on my clients law. I've used Roundup before, it works. Even after a second application nothing. My client was only in town for the weekend and wanted things done. I went back to BWarehouse and the lady who assisted me said the rep will be in contact with me. Needless to say off I went and bought another product x2. This came out of my pocket. My client paid me upfront. I wasn't going to ask him to cover yet another go at **** control. One expect te product to work or am I wrong? 3x days later I get a call from the Roundup rep Tinus Boshof. Hê explained that he now needs to come out to site to see this for himself. I explained the work has been done, I do need a replacement or refund. Not a word further from anyone. Customer service is non excistant in this country. People have no pride and passion for their jobs its just a pay check. Please can the people who work with the public go for customer service training?? You pay peanuts you get ******s. Builders Warehouse is such a household name. How can they not be able to have refunded me and them taking it up with the rep?
