Bad service

My account was in areas, I made arrangements and they requested a proof of payments after I settled the account and I sent them proof of payment. But I can't get any services until after the payments has reflected on their account irrespective of the fact that they can see I have paid. I need to wait 72 hours. I am very disappointed with the fact that they careless of the frustration of a customer. I realized they don't care to loose you as a customer, now I have to wait 72 hours to get assistance in the meantime I must stay wherever I am .
