I am very annoyed that i pay for a service and cannot have access to the internet Using wifi.. "no internet connection available"

I have tried it on both my Xperia Z2 and Samsung S5 with no luck.. It is that bad that i'd have to say that i can only use it about 2 percent of the times.. YES 2 PERCENT.. not a typo.. This is bloody ridiculous..

I have done a lot of research on the net and it seems to be an Android problem.. Spotify works on my PS4, WII and Laptop but on none of my androids.. The mobile is the main reason i joined/suscribed as a premium member..
No point asking me to try to fix it myself as i already..

1.. uninstalled/reinstalled software,

2... Turned on/off /on the phone,

3... Restored both phones,

4... Taken both phones to my mate's house Wifi and

5...Used the community service you guys offer and still with the same "No internet issue"

Please advise real fix for this issue as i am spending my well earned money on a service that i am having extreme difficulty using... You should also have a phone number for direct contact so that WE can contact you and have all our problems/issues fixed 1 on 1..

Awaiting a genuine response
