This is to inform you that I want my phone line be cancelled as soon as possible. I have been having problems in using my mobile phone as I cannot call often. I have been trying to call your customer service support, but they keep on telling me that they will investigate the matter. It’s been a month and the same problem still occurs. I got no action from your company, hence, I think it is better to just terminate your service. I think I am only wasting my money for the services I do not really avail.
I hope to get a response from your end in 48 hours so we can finalize the matter. I hope you can act on this so your other clients would not get affected gravely like your service did to me.
