Excessive charges for returned items

The charge of R138 for each of these items below is unacceptable! I requested all of these to be blocked before they were put through!<br> <br> And either way, how do you justify the massive charge of R138 for a simple return??!!<br> <br> 02 Feb 2016<br> #RETURNED ITEM CHARGED<br> <br> 0.00<br> -138.00<br> MAGTAPE UNPAID<br> <br> 0.00<br> 4,281.11<br> 02 Feb 2016<br> #RETURNED ITEM CHARGED<br> <br> 0.00<br> -138.00<br> 02 Feb 2016<br> MAGTAPE UNPAID<br> <br> 0.00<br> 771.34<br> 02 Feb 2016<br> #RETURNED ITEM CHARGED<br> <br> 0.00<br> -138.00<br> 02 Feb 2016<br> MAGTAPE UNPAID<br>
