Calls over and over and over...systems not updatef

I have made an arrangement in March and I paid which is for 3 months and after that I will have to neg again. I assumed by making an arrangement I won't be harrassed.How wrong I was...as of the 29/03 I have been receiving 3/5 calls daily from different provinces for the same thing.....Does Capitec not update their systems and is it their core business to frustrate and Harass their clients?......Everyday without fail 3/4 calls just to say the same thing over and over and over again....Am I the only Capitec client. This type of behaviour will and need to be reported.....
