No service and Bad service on Walka

<p>Got a walka as a present from my sister ,. Did a chance of ownership on Friday the 24 th after so many ups and downs trying to sort it out Finaly after 17h00 it was now working. It worked on Friday and Sa****ay no problem. Sunday it stopped working after two calls and holding on for 40 minutes it was finally sorted out . In the Middel of a the 8pm movie the walka was not working again . After many attempts to soft reset and hard resets I gave up. I phoned today and the call center could not help me with my problem, she will escalate the problem, after two hours I phoned again same story I will excalate the problem. I was phoned back by a supervisor and he said I will excalate the problem. I'm paying for a service I can't use and nobody can sort out my problem. Terrible service very unhappy as I have been a customer with them for many years. </p>
