Worst ever experience with Zoom Fibre

I am very furious with Zokm Fibre, I honor payments in a monthly basis from the links they provided in order to make payment. I made a payment on the 11th, got the payfast confirmation email that has a refence that the payment was successfully made. My Fibre is not working because they can't pick up the payment I made. I asked them to use the reference from the email, I was advised they are investigating the matter. Now am being told to prove to them how did I go about making a payment while I used their very own link. I don't know how do they expect me to prove anything relating to their link because I don't work for Zoom Fibre, am not their technician and I have provided proof of payment, but they are making chat to agents who just cut the chats. I want sent a whatsapp and ask to speak to Lyall who tried calling me during office hours and am unable to pick up calls from work. Today am told Lyall is not working and will be working tomorrow while am not connected and my money was deducted.
