Non delivery of service

I reported a broken Samsung frontloader washing machine 3-4 weeks ago. Assigned technician from Pro/Lad phoned me and said he will order parts (without checking the machine himself. After a week he reported he received the parts but it was damaged and could not repair the machine I phone the call centre again and requested a replacement but it was declined due to parts being available. After putting me on hold 4 times the operater disconnected the call when I insisted on speaking to his manager. I'm sitting without a washing machine,that is still under warranty, that I cannot use. I have to take my washing to a laundromat and its costing me a lot of money. Please help. They used my cel nr ***) to trace the call nr
