Poor service provider and complaining

My Name is Tume Godwin Lemaoana. I am not happy with the service provider at Zoom Flex I paid my account last week till this day I don’t have connection, their sales agent never explained that every time you make a payment you need to generate a new Scode. Now it’s my problem and am not getting any help from their side or feedback. Now am running after them everyday without help and I have missed work from last week Thursday till today. Am definitely gonna find another service provider and I would not recommend it to anyone. Most of my appliances work with internet but I don’t have one but the payment is reflecting on their say. Am not happy honestly, poor service indeed.
