Terrible Service

I have since the 15 of November been complaining about a data charge added to the incorrect number and needed to be rectified after speaking with several agents I escalated to a team leader fred hayward who confirmed he fixed the error and sent an email confirmation that it has been resolved, 7 days later I receive an message saying my data will be expiring which confused me, as Im paying 160 for 1gig plus 1 gig free which should last 30 days after several emails to the team leader he never responded i spoke to several team leaders after this and is constantly told they are escalating this, two weeka ago I started speaking to ***nor which has been terrible she made me send email after email with no response i phoned several times and still not resolved I expect to be refunded and compensated for this
