terrible service

I had cancelled my netstar tracking contract after i had completed my contract...I sent altech an email to cancel this product in November 2014, a month before my contract was due to expire. I got a reply a month later that it is being processed and that it takes a further 30 days to be canceled. Altech continued to deduct money after the account was closed and when I called they said it's for additional features on my account, which had been closed already. I had asked to cancel those features as well on 16 February 2015. On 16 March 2015 I was notified that altech is still deducting money. The customer service do not have record of my details for the additional features anymore. The consultant ( Glenda) offered little help and did not offer any reason for this issue. I am appalled by the terrible service and will definitely share my experience with others.
