Installation query

I app**** for home wifi on 11/03/2025 and I paid for installation fee immediately. I was advised that a technician will contact me within 24 hours for installation. 24 hours exceeded and there was no communication. I did a follow up with the contact center and they confirmed that there is a technician by the name Gibson who is assigned for my ticket. The agent promised to do the follow up with him and gave me his cell number to contact him, however, even after that call there was no communication. I have been contacting the telephonically and this query is still not resolved. The lady that I spoke to today (19 March 2025) promised a callback but she didn't call me back. I am so disappointed on Jenny Internet they've got a very poor service. They were busy harassing me with the messages, emails and calls telling me to pay the installation fee immediately so that the installation process can be quick but now after numerous calls I did they are failing to send a technician for installation. THEIR SERVICE IS HORRIBLE
