Vuma disgusting

I am disgusted with your service i have been receiving from VUMA VUMATEL .The agent called and whatsappEd me a lot to make paymentfor installation I paid for installation 28/08/2023 but was only HALF installed yesterday the person who was there told me that something is wrong with the line outside a technician will come after 30min at the time it was 11:00 till now no one was there i contact vuma yesterday the lady told me this thing of 30min is not true they just say that there is no call log for my request the technicians doesn't have time they can come anytime it can even be Friday or Monday also I mean huh??? Is that how you train you people for me it's very bad as iam working for a big company in the client service department so again today I contact vuma via whatsapp the told me it wil take 72houers I mean I paid a log time ago for service that iam not receiving the agent who helped me via whatsapp was very unprofessional I've noticed vuma os not there to keep clients I told them in that I I'll cancel my contract without any explanation or doubts the send me a link to cancel iam really very disappointed is this how a new company operate? That is appalling and disgusting and lastly frustrating.
