bad service with damaged goods

I bought a Trimtech 900 watt Trimmer with a cable for R799.00 on the 4/05/2017 at Silverlakes Makro store at teller No 17 cashier no 31. The trimmer comes fully assembled accept the handle and safety guard. I used it for first time first week in October 2017; as it was winter. With the first revolutions the ****l hosing, cutting line, spring and cover got dislodge and flew out. This is very dangerous. I took the trimmer back to Makro three times. The last time I took it back for the same fault I was asked to pay a amount for repairs. I told Makro it's a manufactures fault because the distributor cannot repair it. The last assessment no. Is ********** date 4/11/2017. I told the following people about my problem: Albert Sekgalo (Makro outdoor manager) ********** 527 Patricia Mphaphuli (Customer Services Manager ) ********** 478 My contact details: Mr C W K Seckle ********** 492 ********** I don't want repairs on Trimtech Trimmer as I do not feel safe to use it. I need a REFUND. Makros poor service delivery and blatant disregard for my rights as a customer is shocking. If you draw a report you will find i am a loyal customer and frankly dont feel like ahopping there anymore
