Lack of Response

I would like to express my disgust in the poor service received from the Customer Service/Retentions department<br> On 25/08/2015 I sent an email querying the increase in my debit order, I received a speedy response advising me about a tariff increase. I then sent another email enquiring about communication sent to clients informing them of the increase, to which I received no response.<br> On 28/08 I sent a follow up, to which I received no response!<br> By 17/09 I had still not received a response and requested that they cancel my contract to which I suddenly received a response in which I was asked what can be done to retain my business which I was not interested in, I maintained that they need to cancel my contract in my response on 18/09, yet again I received no response!<br> Sent a follow up on 22/09 to which I received no response up until now!<br> It has been 27 working days and I still do not have an answer to a simple query. Due to their lax service I will have to pay an extra month on a contract, I do not want let alone use due to no fault of my own!<br> I had issues when taking out this contract and again when wanting to cancel it!<br> I would appreciate it if this matter were resolved ASAP
