Poor Service

I have paid for the device and the partial installation was completed on the 30th of April 2021. It is now 11 days later and I do not have a wifi connection as Vumatel has not completed the final installation. Every single day I phone and send mails and the only response I get is "I have asked operations to give feedback and I'll forward that to you once received" I am not impressed. I told them to remove the unit from my home and give me a full refund and even that is being ignored.
