Poor customer service at Idenry clothing store.

I have been paying my account every month and even paying more than the required monthly instalment and I have never skipped any payment since I open the account at Identity. I am so tired of all the messages and calls I receive daily asking me to pay my account with some of the consultants being very rude, unprofessional and giving conflicting messages. I complained to their customer service department through emails and they asked me to send proof of payment of payment which I did but I still receive annoying calls that I am owing. I regret opening an account at Identity as their service is appaling. I wish ther management can do something about this.
