After a decade I'm finally rethinking my choice.

After being a loyal customer for 10years I've over looked most of the problems I came across because I had faith in them but wow its bad...last year I was due for an upgrade got to MTN Clearwater the guy actually did a new application all together that I discovered 6 months later and all I got was "we apologize for the inconvenience". But this time I called them to request an upgrade to get a router instead,canceled my WiFi was told my upgrade will be active in 24hrs its been 4 days and I'm told to wait until Tuesday ,the lady I spoke to told me "sorry there's nothing I can do" I haven't been able to work since last week.if I had known I wouldn't have canceled my WiFi for this unfair treatment. I'm very disappointed
