PATHETIC SERVICE HIGHLY FRUSTRATED

I can no longer pick up signal on my tab 3 and Samsung A3 devices at home. I have no problems doing so at work and in town. Previously I had no problem with my devices at home. I called vodacom so many time to complain. I was advised to change settings and eventually was contacted by an advanced technical team who advised that if the problem is not resolved I must send an email with phone numbers affected, gps coordinates, map location and what not. I was promised I'd be contacted within 48 hrs after sending the email. I sent email on 23 March and have since received no feedback!!! I call in customer care today and was told after giving my ref nr that the matter is with the back office. I asked 2 pls be put thru to the back office and was told no! they can't, I will be contacted. I asked for a number or some means to contact the back office to see the status of my problem and was told no number is available and I must keep sending emails to vodacom customer care. Really cheesed off as a vodacom \VALUED"client. Service is shockingly pathetic. """
