Cancel the contract

Good day I am very disappointed at your service regarding the cellphone contract I took with you and I really do not appreciate getting calls from your customers services because it wasn't paid, but you failed to even send me an email about cancellation policy or notify me that the contract is about to expire. Instead you are so up in calling me for your deductions.

Please kindly note that i need this contract cancelled and unfortunately I won't be paying any money due to i hardly use it and payments where on time but the company failed to even offer me an upgrade or sometime but to quick to look for the outstanding balance
