Cancellation of Subscription

My husband passed away in February 2015. I attempted to cancel our monthly subsription which we had been paying for approx 13 years. It kept being put through my account and eventually I had to go to my bank to cancel this subscription for R46.00. Initially I sent an email through to the customer contact centre cancelling this. Then I sent a fax. Since then I have sent approx 10 emails and numerous telephone calls. Maria rep**** once and gave me a credit refund number CAS-532490-J9T3 and cc Rajan Moodley. Its a long time since I have had such shoddy service. What does a telephone call cost or an answer.<br> <br> Really disappointed with such a large company Altech Netstar.
