Bad service from Metrofibre finance

If I could give a minus I would. Pathetic service from Metro Fibre accounts. I called and the first agent hung up on me, second call, she said hello, I asked for her name and she put me on hold.

Reason for the call was to enquire on the account that's supposedly in arrears when I made payment every month. I send POP and the only month I didn't send was last month, anyway its not like it's a must. I made the lazy finance department job easier by tracking payment. How do I owe over 2 months when I've made payment every month. When will you credit me for the service that was down for over 5 days almost 2 weeks ago? I requested a call back but no one has called me after putting me on hold for no reason wasting my airtime.
