Isabella Garcia has a bad service

I have a contract with Isabella Garcia they called me introducing their products they promised that if their products gives me problem they willing to send all my money back and I can cancel the contract anytime. Then I was like ok fine let me try few weeks later after using their products my skin started to have ****les I called them explaining what was happening they told me they will change and give me a different products then they send me other products still nothing change my skin became worse , then I decided to call them again wanted to cancel their contract they told me I must return their products back to them before I cancel their contract we arranged for them to come and collect their products since most of them was still new because I didn't use them, but still they continue deducting the money every month when I call and ask them to cancel the contract they told me they can't cancel the contract so basically they deducting money for the products that they took it back and they didn't keep their promises since they told me I can cancel immediately and I can get my money back so this Isabella Garcia its a **** and they don't respect their clients
