All paid No service

Ttedo whom it may concern.

My mobile service was suspended without any warning. Apparently it was not paid and no correspondence as well. I bought extra data like previously when data was depleted and nothing gone money wasted. After calling Saturday I was informed they can't help as the call centre had technical difficulties. I must call again. I called today after debit order went off last thursday and was told to wait seven days. So now I paid for a service cant use it and wasted more money so that the directors can have a big christmas bonus on the cost of the consumers. In the meen time they give a fine flunk about my business and money I loose per day because their attitude towards the customer. I had problems with this contract since day one. Can someone at high level please respond to this
