Clicks not taking responsibility for faulty products

My daughter bought the family christmas gifts, clicks smartlife by kambrook. 3 of our blenders packed up after 3 to 4 months of weekly , not daily use. Clicks in Pietermaritzburg cannot do anything about it because they say the clubcard used did not bring up these purchases. My point is that with or without the clubcard, these blenders should not have broken so qiuckly and so easily. We have other kitchen appliances for years that serve us well, like blenders, liquidisers, etc.I want the purchase price of all 3 appliances refunded to us asap. please.
