Nonsense, Disgusting, Unprofessional and Regreting

On the 21st of February I subscribed and made my payment for the installation of fibre. I was told that they would come for installation on the 24th, they came and told me that they could not find a certain fibre and are waiting for technicians which were on their way. They left without telling me and I’m still waiting for those technicians. I have been calling the customer service but with no assistance, there’s not even a feedback or an update! I want my MONEY BACK! This is pure nonsense
