Pathetic Service!!!

I am extremely disappointed in the service received at Telkom Mobile. Despite 7 calls with an average of 45 minutes each - no notes are made on the system. One has to constantly repeat oneself. My debit order did not go through on the 30 due to the fact that the new bank details were not updated. I contacted them to arrange another debit. I was in hospital. They then debit me (a double debit) and promptly disconnect my services. After 4 calls I still have no joy. There are no managers and supervisors are too busy. They never call back. I am told that despite my arrangements and after years with them - (with a first unpaid) - that I was handed over to debt collection and should have my services re-instated after about 10-15 days. Can I then have a refund please because Telkom - once again your level of 'competence' amazes me....
