Vumatel!! worst service ever experienced

I am on my second week battling with Vumatel calling at least 7 times a day, initially it was a failed installation which required fixing, 10 days later which is yesterday they corrected the installation by assigning my device/ box to a different user, now the situation is worse as another person has now been affected. With the help of their installation company, we trying to reach Vumatel and calls are being intentionally hung up, if you not calling for placing a new order they tell you that they are transferring you to reception where you will be directed to the correct people and immediately there they cutt of your call. I made 6 calls talking to the same person and each time she told me that she can only put me through to reception, when I tell her that my calls gets cutoff when she transfers she tells me there is not much they can do. Where in actual fact I was trying to get hold of a Krisendree Kristen who is responsible for our area and my ticket, we just can't get hold of them. I am of the opinion that they cancelled their call centers due to high volumes negative inbound calls they receiving for the poor service complaints. I am at their mercy it seems at this point and the notion " customer service " does not apply in this company.
