MFC DAYLIGHT ******* & SERVICE DELIVERY NON-EXISTENT

I have been contacting MFC since last week. Firstly whenever I call I am asked whether I have consent to deal with the account, after my husband have sent a formal written communication to you several months ago. Secondly for the upteenth time I am asking you, why have the monthly instalment changed significantly way more than the refinance agreement..I have spoken to both MFC and Innovation group consultants, and was informed that the monthly instalment for the power up service plan is R182.11......HOW DO YOU GET TO THE AMOUNT OF R1500 extra plus the instalment making it just a little overR4400, excluding the addded R350 for an extended warranty?? Whenn I requested a detailed calculation your consultants sent me transaction history, I WANT TO KNOW WHY ARE WE PAYING R1500 more per instalment. something does not add up surely a power pack service plan can not cost that much, because if you work out R1500 x 24months....please do the maths as this would not be worth paying so much money for beneefits of on ce a year....I urgently need to know how you got to your extra payment...THIS IS ALSO NOT THEE FIRST I'VE HEARD OF MFC TRYING TO 'CON' THEIR CLIENTS...IT'S RIDICULOUS TO SAY THE LEAST.
