Cool Ideas lack of customer empathy

I have been a loyal customer of Cool Ideas / Vumatel from October 2018. I have never had a problem until today when I saw their black Friday deals on Facebook. I have spoken to Cool Ideas useless Call Centre, 9 different people and they all read from a script like sheep and cannot answer my question. My current speed is 100 / 100 and I'm paying R959 per month!! Now your Black Friday deals come along offering 500 / 200 plus 2 months free for R919!! My package 100/100 plus 2 months free is R669 per month on this deal. Why are Cool Ideas only looking after new clients and not your loyal customers which have stood by you through thick and thin? This is not fair, even on your Facebook pages people are venting their anger and Cool Ideas is deleting all the negative comments from existing customers. Don't you think Cool Ideas could have done something for loyal existing customers before shooting themselves in the foot by offering these fantastic deals to new customers only. There are plenty of black Friday deals with other service providers. Might be jumping ship. Times are very tough for everyone yet we've stuck with you (even during Covid) and you had the opportunity to help your loyal customers but you didn't. You have doubled my speed in the past at no extra cost, however since then price has just gone up and up. So is it worthwhile potentially losing so many existing customers to get a few new ones??!!
