Terrible service and incompetent manager

I would not recommend you this store for any purchases if you expect your items to last. I purchased a Dell Laptop charger her for R300.00 on 8 /7/2020 on 4 /8/ 2020 I returned to store with defective charger. It was swopped out but only part of the cable not the whole unit. 2 weeks later it became defective again. Living away from Chatsworth I was not able to return immediately so I returned to store on 25/7/2020. the sales person who attended to me said that the part that is defective is a free part that they put in box themselves and is not reliable and tried to get me to spend more money offering me another cable for purchase. I asked why I wasn't advised that on purchase that the unit was unreliable and should have purchased another extension in addition to what was already given. His excuse was the salesperson who dealt with me should have advised me. I told him that I cant be held responsible for their sales people not advising me. The manager, a lady definitely not competent for the position. looked at the receipt and said if it lasted for a month its fine and not their responsibility. who would pay R300 for a laptop charger to last a month ?? Her then excuse was' I don't know how you store it in your home' this after already being told by the sales person that the so called free part was not reliable. This alone proves they are selling defective parts to the public without intention of taking responsibility. I would think twice before trusting this store if you want your item to last more than a month .
