Still awaiting refund after service has been cancelled.

<p> I cancelled my ADT service as I am in the process of selling my property. I sent them an email on the 6th of April explaining this to them and required from them how I should go about doing this. They responded via email informing that I have to give a months notice and thus would have to pay for the service for the month of May hence they would debit my account at the end of April. I was happy with this arrangement and still agreed that i would send them the details of the new home owners. To my surprise I got debited again at the end of May. I immediately contacted the person dealing with my account Nadia Israel and she informed me that she would get back me wrt when they would refund me. I am still waiting for a response after 21 days.. I finally went to to the Port Elizabeth branch on Friday 17th June to find out when i am receiving my refund only to find out no credit note had been raised. I went there today again to enquire when I would be receiving my money and was told they would inform by today. Still no response. I had been a client of adt for more than 10years and after this experience I would not recommend them to anyone. Your staff do not know your procedures and lack honesty and integrity.</p>
