Dissatisfaction with Defy 's service

A week or 2 ago , i logged a call with Defy South Africa to repair a fridge for me. They advised that i will be liable to pay the call out fee fort their technician. I did not have a problem with this . Their technician came and he was so rude with us and very impatient , threatening to leave without assisting . Mind you he had not arranged his visit with us as the family since we are working and it was a business day when he came. He finally got to our house . He advised that our fridge fan was faulty and required a replacement . He said he would remove and bring back the new one . For the last week , i have been doing a follow up with them their call centre , without any assistance. My fridge is not working . I am so frustrated by Defy .
