Terrible call centre en error clearing service

I have been trying for 3 hours to clear an error message. First I used self service and the problem was fixed. Then the same E16 error showed and tried rsolving it through self service. After 30min no progress so I phoned your call centre. Call no 1 lasted 16 min and the lady stuggled to resolve it and she was was unfriendly and sounded very annoyed and the call dropped. Call no 2 straight after lasted 26 min and the lady agent again put me on hold and the call dropped again. Needless to say my decoder is atoll mot working after several failed attempts. This is terrible service in fixing errors!!!!!!!!!
