No aftersale service

I have taken out a contract in December 2014 and since I have problems with the company every month my phone is blocked. Numerous times I have phoned them to find out what is the problem. Only to spend most of the day trying to get them to answer the phone not to mention that you never get any feedback if you manage to get hold of some one. Many times I have to tell the same story of debit order not activated on their side after giving the information so many times.I did go in to the office aswell and try to get them to correct the problem. It is costing me money every month to get them to correct the problem and still it happens every month how many times do I have to explain the same problem really this is ridiculous.
