Item return issue

I bought a lot of things from tfgonline weeks ago and because they didn’t fit I requested them to be fetched and returned since I’m in a small town I can’t do an in store return. I filled the return on the 17th of March, they told me to wait 5 to 10 days but even now I haven’t received any confirmation for the return pick up. I keep calling but everyone that answers says that my return wasn’t logged in the system and that I must wait another ten days , about five people have been saying the same thing which is very unprofessional and really disrespectful. If you buy your items somewhere else because it becomes a hassle if you want to return the items. Until now no one has helped , it feels like I’m being ****med because at this point I don’t think I’m getting my money back
