I called the Sky CS people a week or so ago - had a voucher code that gave a free film rental, and there was no obvious way to use it, so rang up for help.
The chap I spoke with was Bulgarian, which he voluntarily told me, after he asked me what the weather was like in the UK, and I asked likewise to him. He was excellent, and then as a kind gesture offered to give me Sky Ultra HD free for a month as a trial. Lovely, I thought....
... Got an e-mail three hours later on, and he'd removed some of my Tv package, "upgraded" me to stuff I'd not asked to do, and added things on a higher price tier than I needed!
I was not best pleased, and so I rang back, and spoke to a lady in Bangalore, and she explained that I was wrong, and that nothing had been altered on my account, even though I had e-mail proof showing otherwise.
Had to then waste another 20-minutes fighting with her about it all, and getting her to undo all the rubbish nonsense that the Bulgarian chap had done to my account.
Really hacked me off hugely, and I was then asked to rate her service with at least a 9, as it would help her out hugely - her words, not mine. I didn't rate her at all, and if I had, it would NOT be a 9 she'd be getting but something significantly lower.
This kind of garbage, is why I hate dealing with overseas call-centres who not only do I struggle to understand their heavy accents and speed of speech, but the constant accusations that the customer has "misunderstood" something (i.e. we're thick) or that we are "mistaken", when we have stuff right in front of us in black-and-white proving our issues, is really not good.
I would have used the Live Chat service instead, but that was broken on the day I wanted to use it.
Sky needs to sort out its CS. I don't care where someone is based, or what nationality or race they are, but if you can't speak clearly, and aren't fluent with English, then please don't do the job. Heavy accents across international phone-lines, is not a helpful way to deal with customers.
