Reactivation of account

Absolutely shocking service with totally *********** people in employment. I have been trying for over a week to reactivate my number. I completed all the necessary documentation, paid the contract fees, bought new sim cards etc. After the waiting period was over, I contacted them to tell them is hadn't been activated, only to be told the documents hadn't been submitted. I had to contact the shop, which I did. They couldn't help me. The call centre people just say the account has been deleted. No one was able to assist. I contacted the Regional Manager and things seemed to move a bit after that. Each person in the call centre puts me through to another department and they in turn put me back to the customer care. The time spent calling from a landline will reflect heavily on my landline bill! One sim has now been activated and no one knows how to correct the problem with the second one. I called the Head Office and... was put through to a call centre AGAIN. So I have a contract for which I am paying - and no service. Incompetence is an understatement. One has to wonder how the company is still running.
