How do I return your products when no one ever call me after repeated promises to do so for almost 2 weeks?

I have spent over 6 hours on the phone to your company this week, I have has 6 promises to return my call, I was on the phone today for 45 mins, I was told to hang up the phone as your English speaking person was waiting to call me immediately - I asked to just hold or be put through, told that was not possible so very reluctantly hung up.

So 4 hours later I am still waiting for the call ......

So please do not expect me to call agin, and do not offer the phrase “ we must speak with you Mr. Jonathan “ “ to help you Mr. Jonathan “ I have had that 10 times this last week alone !!!

I am only trying to return your equipment, I spent 3 hours driving to Loules store to try again to get help - it was pointless - I am only polite, ask for help and get nothing.

NOS incorrectly fitted a system I specifically said I did not want, N.O.S.have wasted 4 days of a 2 week holiday ... I am sitting waiting for engineers that do not turn up, or on hold, waiting for calls that are never made to me or messaging NOS for help.

I ASK YOU ..... HELP!!

I tried that once, will do again .... on my way to the airport, I will hold it up, take a nice photo and leave it with them ... thanks for you time in helping me 🤗
