Warning against Amazing Vouchers

I want to warn consumers against this company. When they offer you stuff it sounds so "amazing" but when it comes to delivering it is terrible. I subscribed to Amazing Vouchers but after doing research on the internet, I contacted them back the next day to cancel the subscription. The number they gave me for the business does not even work and I had to phone the legal assistance number to get hold of Amazing vouchers self. Needless to say I followed up on my cancellation a few days later and they assured me that it was cancelled but 2 weeks later I got an sms from them welcoming me to their company. I phoned them back...again through the legal assistance number and the operator told me that I will be paying a cancellation fee. I cant believe they charged me almost R300.00 to cancel and I have not even made use of their services. The vouchers they offer is mostly for people staying in the Cape Town area and is of no use to me in Gauteng. Please people think twice when you are called by this company before joining, it is a hassle to cancel and the offers they give is not as amazing as it sounds.
