Unsatisfied customer

Brought a Defy fridge Nov 17, reported the fridge in the beginning of the year. That it as a faulty and damaged. They fix it first and still the fridge had a faulty in the same place. Reported it again, since February this year we have no fridge at home but we are still paying the installment every month. They refuse to replace the fridge or do something about it. We lost all the cold chains in the fridge they are just playing hind and seek with us. And not taking our problem seriously. We've been very patient with them, no communication at all. We as the customer have to phone them or go the they branch in Gugulethu mall where the fridge was bought. We are not satisfied a the customer at all. But the what us to be like sheep and sleep it off. My mother high blood pressure is up due to this. We can't even buy mean or the kids school stuff cause we don't have a fridge the store things. And buying one by one expensive too. The service sucks big time. They don't care about us they just wanna make a quick buck only. We pay for service rendered but what service are they really rendering to. Cause they don't put us needs first at all. Bradlows have a 2yrs guarantee and Defy a 5 years guarantee. Please don't buy in this companies they just don't care. Because when she is finished paying for the fridge she has to pay R25200 for something that is not working. They are no apology at all, that is why I'm so furiously. Because do know what they are doing is wrong in all angles. And Easter around the corner we have to beg them for the service. They need to train they people about customer service and how it works too. ? ? ? They don't get even 1 star cause they have failed completely
