SMARTY acting irresponsibly

I am disabled and elderly. I support an even older mother who lives six miles away. I am also a telephone befriender with a society which has elderly and disabled members. We all phone and text a lot. I phone my mother twice a day. I phone other relatives as well as friends. Today, SMARTY took £8 from my account by Direct Debit. A few hours later, SMARTY paused my account without warning. When I eventually worked out how to contact them, I was informed I appeared to be running a business and using their service. I am not. I was then told that my use of texts indicated I was spamming. I am not. In shutting down my phone, barring all incoming and outgoing calls and texts, SMARTY brought chaos to my day. I am still waiting for a resolution to this. They have acted completely irresponsibly and although I have been with them for several years, this has completely changed my opinion of them. I have approached Trading Standards and the press as I believe this is such bad practice on the part of SMARTY. Today has been utter chaos. THANKS FOR NOTHING SMARTY. I am very very disillusioned with your company.
