Phone calls to paying customers.

Good day, I have a Home Choice account since May - Acc ***, where I purchased 2 blankets for the winter. I am a loyal paying customer, I make a payment every month, however every month since May Home Choice keeps calling me numerous times to find out when I am going to make payment. I feel this is unnecessary and have to wonder do they make as much effort to the non paying customers? I would appreciate it if Home Choice would stop calling for payment as they receive their money every month from me and focus on non paying customers. This type of service will result in Home Choice not receiving any further purchases from me.
