..but I always pay..

I always buy from Homechoice. For the past 3 years or so I have been paying on time, without skipping a single month. It drives me nuts when I receive a call, asking me as to when I will pay my installment. Even if I indicate that I will pay before the end of the month, they still want me to give a specific date. This call comes even before month end. To me it sounds as if I am not a trustworthy customer. It sounds like they are not sure if at all I will pay. I have to think twice before I order anything from them again.
