PATHETIC SERVICE...SORRY, NO SERVICE

My line was disconnected on Saturday 30 May 2015 for some or other reason. I couldn't get hold of anybody and was told that the call center was closed because of a strike. So by the Tuesday, I was still not able to get hold of anybody so I called a store. The lady took my number, did something on the system and told me to switch the phone off and then on again.it worked then but she couldn't tell me what the problem is.I received my monthly billing with an account 3 times what I normally spend on the account with charges that for one doesn't make sense and secondly did not add up to the actual balance of the statement, it was like the statement and the invoice charges did not belong to the same account. I called the call center and surprise surprise, after 27 minutes I put down the phone. I called the same store , the lady told me \sorry can't help you
