Payment allocation and poor customer service

From march I've been experiencing same problem where I make payment for my account but a day or two after I made the payment they disconnect my services have to phone which they keep you on forever. They reconnect but 5days after they disconnect again. This month it's even worse I don't know how many proof of payment I've sent. Spent whole day yesterday on phone with they can't see payment. Finally they see payment but it's gonna take them an hour to allocate the payment then they will reconnect my services, even it's not reconnected.. I've never such poor service they don't even have an audacity to phone me to say what's the hold up. Even today who have phone them and find out why my services are connected which they will keep me hold for too long. I am very disappointed wish other option would've cancel my account with them
