of do not reply but replied

I got this SMS this afternoon.

"XXX:Thank you for your recent visit to Cycling & Carrier XXXXXXXX. For any enquiries, please contact us at 6XXXXXXX.(Please do NOT reply this SMS)"

I had sent my car for its regular servicing yesterday. I guess this SMS should be sent by the service centre. It's their way of saying thank you for patronising their centre. The handphone number of the sender was one that I was not familiar.

Feeling bored. I replied against the sender's request.

"Hi there. I'm replying you to say 'You're very the welcome'. There! I've replied against your wishes. Happy April Fool's Day.(Please do NOT reply this SMS)"

I got no further response from the sender.
