Swift Funds Swift Funds Financial No documentation...continued calls

I signed up for Stretch Zone in Greenville, NC in May. I received services until the end of June at which time I hurt my back and was unable to return due to no fault of Stretch Zone. I was advised by my medical provider not to continue services. I advised Stretch Zone of this after several attempts to contact them I was able to reach them via FaceBook Messenger. They tried to talk me into continuing but I advised them I would follow my treatment plan and asked for a refund.

They told me to get a letter from my medical provider and they would send it to corporate to see if I could get a refund. I have heard nothing back. Until a couple of days ago and now apparently I have been turned over to a collection agency for $469.00 for services not received or requested. The collection agency said it was because I did not cancel my account. I am not really sure how that is possible since I obviously told them I could and would not be back and had even requested a refund. I have reached out to the company to make sure this is not some type of SPAM, but again I have not heard back.

I never received the first call, email or statement in the mail regarding any charge or payment due. I do not understand how people can do business like this.  I would obviously like for any "debt' they think I owe to be erased and my credit restored (if it is in fact in jeopardy) and I would love a refund for the month I was medically advised not to go. I would also like for any other consumer to be aware and BEWARE of this company. 

Swift Funds continues to call and say they have sent an email which I have not received. They said it is something wrong with my email...it is yahoo...there is nothing wrong with yahoo....I have never received a statement of any kind from any one...just threatening phone calls. I am 40 years old and have perfect credit. This is ridiculous!
