Bad customer service

I'm not happy with the service at all I have 2 contracts with them and the other one was expiring last month,I called in June to put notice but the consultant told me to call again in July,I was surprised because I new my contract ending on July and wanted to serve 30 days notice. I've sent emails on time to customer service but still my contract is active now on month to month basis.Went to the branch to query was told it will be cancelled in September. I'm so angry
