Keeps on phoning my wife, my employer and myself even though there is an arrangement in place

<p>I have made arrangements with MBD as early as February this year to make payment in the amount of R500.00 each month. Payment is made every month even before the end of the month. They how ever keep on phoning me each month end up in harrasing me anf my wife at work. Askinf eilither for an higher installment or requesting a debit order in order to reduce the instalment. Pleasr stop phoning. I dont want a debit order as i dont even own a bank account and my wife is paying the installment, i cannot pay the whole arrears amount and they should stop phoning every month just to hear the same thing over and over again. The arrangment will not change!!!!!!</p>
