BAD SERVICE

On the 19 Jan i had gone to Hirsch in Hyde Park where i was shopping for an appliance and whilst I was there i had brought to their attending that my washing machine and stove that there was problem with it and as i had an extended warranty if they could please send someone out to assist me. The machine was sorted without an issue. However my stove is still an issue. On the 27 Jan someone from Linden Appliances arrived checked my stove and said that we would need to replace to things and would be back the Friday 31st Jan. Clearly this did not happen and still no one has come back. I called Hirsch's repairs/parts dept on the 18th Feb spoke to the lady there and she said will find out who is handling this and come back to me (yet she is the same person i spoke to on the 19 Jan). She still hasnt come back to me. I called Hirsch again today (18 Feb) to speak to the manager of the store and was told his on leave today and asked who would be his second in charge. Was told Mbali and that they would give me a call back. SURPRISE SURPRISE NO CALL BACK AS YET. I clearly havent learnt from my previous experience with Hirsch that the CEO of Hirsch had to get involved. Lets see whose brave enough to get this matter sorted. In the meantime i cant use my oven. Either Hirsch finds a replacement to Linden Appliances or they will continue to be embarrassed by them as this is the same company from my last experience. Or maybe i forgot to ask the technician and the lady at Hirsch repairs which year would i hear from themn
