3 months no Fonepad, no repair, no refund

I purchased a Fondi Fonepad and Fondi kids tablet at CNA 16 December 2014. By 08 April 2015 my daughter's Fonepad started freezing and would not charge. We sent it in for repairs and received a replacement by middle June 2015. The new replacement also started freezing once again and eventually would not switch on within a week, with screen also cracked of which we were prepared to pay for, we returned the Fonepad for repairs, dated 09 July 2015, even though the cracked screen was non-responsive. After one-sided follow-ups and payment for assessment fees and repair fees of over R300, we were eventually told the item was outdated, irreparable and the parts could thus not be sourced, dated 08 October 2015. During this time my son's tablet was also replaced too. This Fonepad is still under guarantee... The store manager was totally unaware of the issue until I demanded the matter be escalated 03 October 2015, hereafter he needed to make many calls to verify what was happening, and now my problem cannot be resolved because now the supplier needs to make a call??!!
