Appalling service

Horrific customer service! I’ve received a call from their collection department for missed payment. I acknowledged that I did not pay. I then asked the agent to look at my records because I’ve made them aware that they could take the funds from my account cos at the time of my debit date there wasn’t any. The agent then advised that she will submit a request to deduct the momey the next day. Next day came, no debit. The agent collections agent then advised I’m not calling you for that I’m calling you for the money. I was shocked!!! At her response, I then told her that she needs training, no customer service skills whatsoever, she then dropped the line on me after I told her I will pay month end. The next day cellc debited my account and again no funds, baring in mind that I made it clear there will be funds available month end. To top it off my account has been handed over for one missed payment along with me making them aware of my circumstances and when payment will be made. I had 5 contracts with them, I’m down to 1 and this is the sole reason why. Pathetic signal and appalling customer service.
