    I was told that all the problems with oppo have been sorted. It was not. I got in touch with oppo and there was indeed a problem with the @O2 network with oppo. The problem phone's oppo highlighted was the oppo pro Reno 8 and the flip and other few phones.

  • Mistro4ndy Andy Hunter (@Mistro4ndy) reported

    Service from @O2 and #dpduk is disgusting. For someone to open my parcel from inner part, take out my new phone, take that and the cable, put it back in then deliver it looking like any other parcel and nothing is being done.

  • DavidRedshaw9 DavidRedshaw (@DavidRedshaw9) reported

    @O2 hi, my tracking number doesn’t work for my delivery. Can someone help please

  • badassscotsman BigYin (@badassscotsman) reported

    oppo even sent me emails telling me this. But @O2 refuses to accept it and blames me or the phone. But they did however blame the shop assistant that sold me the contract and offered me 50% off my next bill. But I still am having the problems

  • JulianMStraker JulianStraker (@JulianMStraker) reported

    Seems the only way to get hold of a business is via Twitter, @O2 provide a simply hopeless service and then refuse to engage. I guess they rely on customer indifference when it comes to moving so take no interest in trying to resolve or explain issues they create

  • bigT__26 Tel (@bigT__26) reported

    Not a nice way to reward a 15 year loyal customer. The person I spoke to today couldn’t care less and her attitude stank quite frankly. Thanks for nothing @O2

  • champagny2 iom (@champagny2) reported

    @O2 Great but how about getting a decent signal here in the UK!

  • SiKavos SAS ULTRASONIC (@SiKavos) reported

    @O2 messaged nearly a week ago. No help whatsoever !! I'm so glad I left when I did! They are quite possibly the worst network! Avoid!

  • NathFerguson Nath (@NathFerguson) reported

    @VMO2News @O2 @UswitchUK Yeah the the network which never works data speed is constantly slow and useless and you rip off your customers with your prices meaning we pay more for less.

    @O2 hi, can I please get a reply to my Odeon voucher not working?
