No Internet connection as promised.

In the last 4 months I have been with Metro fibre I have been greatly disappointed by the lack of customer service, last month I only had Internet for a week, but paid R399 for the full month, when i called the call centre they gave me a reference number and told me that a technician would come at my convenience, which never happened the network finally got repaired beginning of this month but only for a 6 days, after there was a technical glicth, when I phone the call centre and asked if I will be refunded for the month of September they said , but they can credit my account, but crediting any account takes 30 days, and till there have been no updates.
