How long to respond to complaints?

[COLIN30B]

I just wondered if anyone knows how long Sky takes to respond to complaints? I received an acknowledgement which included a reference number but have heard nothing else since.

Sky say:

"We aim to respond to your complaint and agree a resolution within 10 days. Some complaints, depending on their nature, could take longer to resolve, especially if they’re technically complex. If we’ve been unable to agree a resolution for your complaint within this timeframe we’ll contact you."
