The Poorest of Poor Service

About 10 days ago my 5 services were suspended due to "non-payment" When I informed them that I was paying by debit for decades, they told me that the debit order was not presented for payment because their upgrade could have caused it. They will correct it and apologized. Within a week later the same story. Again, I called and held on for an eternity and again I was told that my services have been suspended due to "non-payment" and that they had no record of my debit order. I gave my bank details again and the gentleman also confirmed the writeback of all the fines for all the reconnections, and humbly apologized again. Today I was informed that the service at one of our self-catering units was not working. I again I called the client helpline and held on for eternity, again the noise of people in the background was overwhelming, again I was transferred between people and had to hold on for eternity until I was told that they could turn on all my services if they were allowed to debit my account with an enormous amount.. When I asked how they got to the number, I again had to hold on for eternity. Eventually the lady told me that everything has been sorted out. When I asked her if all 5 services were working, I was placed on hold until I fainted with frustration. Now that I am back to my senses again, I just must state that no one could give me the contact details where I could file a complaint. Furthermore, I had to pay for these marathon calls out of my own pocket because they cannot make outside calls.
