Charged on a closed account

<p>I settled my account with Fashion Express "FIX Account" in 2015, Now in 2017 suddenly I owe them money the sms's started coming in April I thought okay must be a mistake then it came again, I called the number on the SMS spoke to the lady who confirmed thatthe account has not been active for a long time I explained that when settling the account i fully stated that I am closing the account she understood then the connection broke (the I though she had fixed the problem). Next thing I get an SMS with a higher amount I called teh number on the SMS, was told they cant help me I must call another number ending with 7666 option 4 which hangs whilst I'm being charged for the call. I made 6-8 calls trying to resolve this and been taken to this number to another. I kept asking for refference numbers and I wa stold they don't have reffernce numbers. The last lady then told me I must go to the nearest store I asked her at who's expense after been taken from pillar to post and even worse I'm heavily pregnant and I'm not about to be searching for a store that is failing to resolve an issue they started on a domant account.</p> <p> </p> <p>I'm annoyed by the SMS's and threats and when you call the numbers on their threat sms's you still get no help is this a way of TFG/FIX of making money from previous customers?</p>
