Frustrated customer because of stupid home address

Wuuuuuu I have never experienced such horrible service in all my life. I have been through many bad services but Vumatel tops it all shem. So the whole of June we were not at home so I didn't see the point of paying for the service when we won't be home. So we came back end of June, So since I have been trying to get a payment link so that our line can be connected again. Since the 1st of Jun if not earlier I've been seeking assistance. They say they want to verify my address coz on their system the address I am providing is linked to someone else who is not me. So now I want to know how did they lose my address in the 1st place? And I have been their customer for two years if not more. So for just skipping one month and boom they lose all my details? Now we can not get a payment link coz they can't verify my address. When they were seeking for customers, the managed to find my address nice and smooth so what is the problem now? Their WhatsApp line is takes forever to be attended to n when finally someone attends to it then you don't get the service you need. They said I must send a copy of my ID and proof of residence which I did. Then they come back saying the proof of residence must be a municipal letter. I told them the municipal letter is under my father's name. Yoooooo mina I am so frustrated by their lack of service for real. They are not taking their customers serious. Today it's the 8th Jul and we r still not connected just because they cannot very my home address. How was it verified when they were persuading me to be their customer?

Yazi I really don't know what to do anymore.
