Cancellation request

I requested for my contract to be cancelled on the 7th of January 2016 and this still hasn't been actioned. Upon doing the cancellation I was advised NO FURTHER funds would be deducted from my account. However, a payment was taken in February as well as in March, I also incurred failed direct debit charges due to this. I called twice today & was promised a call back on both occasions which never happened. I called the third time at 5:45 & was advised that the people working in the admin department had already left even though they are supposed to be working until 6pm. I was also advised that they do not make outbound calls. This is completely unacceptable. I moved recently and cannot find the copy of my blue receipt & all I wanted was for someone to provide me with the receipt number. I provided the date (07-01-2016) My name A Hendricks & my mobile number ***. I believe that is more than enough information to locate the receipt in the \January receipt book\" which is what the first lady I spoke to told me they would need \"to find\". The service I received today, was appalling. I expect a full refund for all the charges I incurred & I will be taking this matter further."
