Unwarranted charges for BIS

Dear Sir<br> <br> After 2 Years without a Blackberry Phone, I just now realized that Nausua Mobile charged me for BIS - R59 a month. How is it possible to charge me for something that I do not have?<br> <br> In light of the aforesaid, I herewith claim an immediate refund in the amount of R1416.00 (R59 x 24).<br> <br> Your urgent response in this regard will be appreciated.<br> <br> Yours faithfully<br> <br> Anneke van Loggerenberg
