Complaint Regarding Unprofessional Sales Call

I am writing to formally express my dissatisfaction with a call I received from one of DSTV's consultants today at 3:40 PM. The call was both unexpected and highly unprofessional. The consultant informed me that my current decoder would soon stop working and insisted that I purchase a new one. They mentioned that the decoder is available at stores like Game for around R5000 but pressured me to buy it directly from them "for a better price" on the spot.

Given the already high subscription fees I pay, I find it unreasonable to be asked to incur additional costs for equipment replacement, especially in such an aggressive manner. This experience has left me feeling that DStv does not value its loyal customers, as this type of call and approach does not meet the standard of service I expect.
