Pathetic service and no resolution to problems!

It has been almost 2 weeks with absolutely no wifi, resolution to my problem or atleast a timeline. I am beyond frustrated at this moment. It is quick to take the monthly payment at the end of the month, but when we have a problem you are so slow to get it sorted. I have been logging call after call sending email after email. And still nothing. I have been using my wifi for 9 months now at the new premises, no problems, now my wifi is off, openserve came out and said Vox did not link the correct B-number to my account. I get on the phone to get it linked immediately, 24 hours later still no one has even contacted me or linked the B-number that should've been linked 9 months ago. At the end of the month I need to pay for a full month where I have only used the services for 2 weeks. This is frustrating and pathetic service to say the least. I will escalate this as high as I possibly can.
