Bad service

I called in the morning to schedule an appointment for fitment of tracking device in my car, the lady who was assisting me informed me that they'll only accommodate me next week and i pleaded with her to check if there's a technician that is on stand by and can be able to assist after hours. She checked and finally managed to get me an opening for today at 16:00 in Soshanguve. I made arrangements to get home on time. As time passed by, i called cartrack to check if the technician is coming only to find that there's no booking for me for today. I scheduled an appointment for tomorrow at 11:00. Since well tge contract expired on the other car, i saw an opportunity for technician working on both cars on the same day. I was transferred from one agent to another and had to explain to almost 10 agents the same thing, I'm using my airtime by that time and it's like they don't care, they putting me on hold until I hung and call again. Explained everything to all over again. I felt like I'm not valued at all as a customer.
