DISASTROUS RETURN PROCESS

I logged a return on 8 August and was told the courier company will be intouch within 3 to 4 days to arrange collection, 2 weeks pass I get no contact or update on my return. I contacted adidas on 19 August and was told they logging a new return as the 1st one didn't pull through. I wait another week, no contact about my return collection which prompted me to call adidas again on 27 August, again another new return was logged by the agent as priority and was again assured Courier It will will be in touch. Today I phoned Courier IT they confirmed no return has been logged for my order... at this point I've given up I have a total of 4 return requests and I'm not expecting anything new.
