Poor information and service

My cellphone contract expired in February and I delayed renewing as I was waiting for the new S6. When I received calls from Autopage regarding upgrades, I asked for info regarding what phones are available and the contract details to be emailed to me -I received NOTHING! Three weeks ago, I called the call centre to cancel the contract-I was told it would take two days to cancel as my contract had lapsed. I didnot cancel at the time as I was going to Cape Town on holiday and didn't want my cellphone to stop working. Today I called and I am told that my contract will only be cancelled between 23-28 June. When I told them what I was told three weeks ago, they said that this is the policy and there is nothing that can be done to help me. When I asked whether I would receive any notice prior to my cancellation- I was told no and that it will happen anytime between 23-28 June. What **** service and I have been with Autopage for over 15 years!!!! So much for loyalty!!!!
