You'd be wasting your time emailing customer services, I've had dealings with them regarding a pushchair I brought, that in daylight was 2 different colours instead of 1 wtf?
Anyway after 3 months of arguing they finally agreed to order the correct parts free of charge. I wrote to them asking when the parts would be in my local storw for collections as they said 2 weeks and it had been 5 so I then got a letter back from one of the customer service staff to tell me that I'd been contacted 3 times by their staff and twice they had spoken to me. And basically accusing me of lying.
I was fuming, how can they have spoken to me when they don't have my number

So I sent a letter stating that they had no contact number so how could they have spoken to me twice and why would they need to speak to me twice, surely 1 phone call to tell me the goods were in my local store would have been enough.
The reply I got...the goods are in the post to me and the branch will telephone me in a couple of days...wtf *bangs head against the wall*
Turns out the parts they ordered weren't right and I still have 1 thing that doesn't match.
And needless to say, I never did get that phone call.
But I've had enough

I've spend near on £1000 in there and that's how you get treated.
