Shocking warrentee repair service!

I bough a Bosch fridge/freezer combo just over 2 years ago. It was one of the more expensive models. I also took an extended warrentee. The fridge part of my appliance stopped working while I was on holiday. I reported the problem to Hirsch’s on Tuesday, 14 Januarywhen I came back, who reported the issue immediatly to Bosch as I got a Reference nr through an sms. Hirsch’s phoned and did regular check ups to check if Bocsh came out ect and also informed me that Bosch changed their warrentee conditions and that the customer are now responsible to pay the call- out fee and that they only pay for half an hour of labour and that the customer must pay the rest of the labour. I feel it is very unfair, as it was not the conditions of the contrat when I took out the warrentee. The Bocsh technician came out on Friday, 17 January. And told us the parts was going to take 3-5 working days. I received a call on Tuesday, 28 January that the part was received, but that a technician can only come out on Monday, 3 February. The tecnician also mentioned that the PC board may also be damaged, but that he will only know once the one part is replaced. Meaning that it will take another 2 weeks if he needs a PC board . So I can be without a frige for over a month !!! That is shocking service Bosch!!! And you are suppose to be one of the better brands in SA. I also lost everything in my fridge as we were on holiday!
