Frontline Refrigeration & Washing Machine Service

We had just moved and with four little kids under my feet my fridge breaks down. Frontline came out and fixed it with a new heating element cost $230. was very nice and came out on day of call. Only 2 months later my fridge broke down again, so I called Frontline to come out again. The non genuine heating element they replaced only two months ago blew. He said that this sometimes happens with the non generic parts, but told me not to worry cause they had a genuine heating element to replace it with. I said to them 'that's all covered under the warranty, I don't have to pay any more right', and they said 'no I will replace it under warranty, but you have to pay $60 for a call out fee'. I asked them why and they said for petrol and stuff... they only came 10min down the road! My fridge is in pieces and they have the new part in his hand and they asked me 'so you want me to fix it or not?' Not happy! Will not use Frontline again!
