I phoned to make a schedule to update my unit, I was transferred to another department, then I spoke to an agent, he was very nice, he ask to put me on hold while he is checking for technician, I was on hold for long until my air time was depleted, I thought he would call me back since he already ask me for my no's and he made me hold for long, he never called me back.
