Bad service

I'm not happy with your service. I called you guys last month reporting the sim card that I lost and I didn't get any assistance. I called more than 3 times and the 4th time I was told to log the incident online. I did that and the feedback I got was that I should wait for finance department to draft a quote for that lost sim card. I'm still waiting even now and it's been weeks. I didn't pay my invoice for this month because I'll be paying for nothing. Ticket nr: SST554856
