5 Months, broken unit, RONAL PRINSLOO WONT HELP

On the 9th of the 8th month 2014 I purchased a Trojan Solo 250 from Game Store Queenstown. It broke with a month and a half of purchasing the unit. We have been dealing with TAGAN in Walmer, PE. He has, since last year, been a now show to fix unit, unavailable when we phone the offices in Walmer and does not answer his cell phone. Desperate to get answers out of TAGAN as it is already the new year, I phoned the offices in Walmer within the last week of January, and purposely did not give my name, he must have heard I was making all sorts of queries as to the number of the head office and managers who work there so he took the phone, once he heard it was me, he told me the unit was obsolete, so was the part to fix so he would organize I go collect my money from Game stores. I LOOSE ALL THE WAY. I phone the Head Office to complain, the individual who suppose to help me with these type of complaints is RONALD PRINSLOO, but apparently RONALD CANNOT CALL ME BACK BECAUSE HE IS AT THE DENTIST, VERY BUSY. ONLY COMES TO WORK LATE, TAKES OFF \ALOT"";OR HIS CAR IS THERE BUT THE OFFICE LINES DO NOT WORK! I DEMAND A REPLACEMENT IMMEDIATELY """
