Frustrated and Mad!

I have never been so annoyed in my life sadly by a company as big as this, I've been a client for a very long time but lately I even regret wasting my money on you for the service I have been receiving lately it's took me long to even come on this platform and complain because I was hoping you will change your ways and do better but 2 months later here I am still no solution to my problem am disappointed in you as a company and your call centre agents they're making sure to frustrate us even more when we take our time and airtime to call yet they don't help!
