I called to O2 customer to changed my address for my two contracts. When they did so I received a confirmation for my new address and appointment, but the address on the technician appointment was wrong (probably a typo as only one number was missing). Actively when spotted I called to tell their mistake, they promised my appointment date wont move and that my new address is already fixed.

The date of the appointment the technician did not show up. I call again and they said my address was wrong again and that I WOULD HAVE TO WAIT FOR a new appointment (probably 3 weeks later they said).

I work from home and internet is vital for my work, knowing that was their mistake why is not possible that O2 gives priority to a customer and send an immediate appointment to connect the DSL?. 

The only solution they gave me via phone was not to charge me the connection twice. But not a new appointment closer. Not even a compensation for the additional GB I have to buy for operation my job. 

I hope I get a proper customer service answer on this,
