Lost a loyal customer

I was a loyal and happy customer for years until they let their service go down the tubes. I waited over 6 months for my fibre order after Metrofibre installed what they needed to at my premises. I enquire 4 months after Metrofibre did their work only to find out that Metrofibre cancelled my Webafrica fibre order because I have another fibre line installed for my tenants at the same property. I enquired why Metrofibre was allowed to cancel on my behalf and not informed worst of all.When enquiring why Metrofibre could over rule me the paying customer all they would say is that I need to place another order! Surely I was sane when placing both orders? I'm gone. Never coming back. Too bad cause I was happy.Lord help me cause I still need to deal with Metrofibre with my next ISP...eeeeeekkkk!
