Terrible Customer service

I should have given you 0 rating but unfortunately there is non. Bad customer service from your agencies, they drop calls on my ears while I'm still waiting for assistance. I took a contract phone from them, they never sent me not even one invoice or statement they just keep on adding unknown charges to my bill and when I call the call centre they just drop the calls without any assistance. I went to 1 of their branches in Greenacres Port Elizabeth and I was told they can't help because I did the application online they only deal with in store applications. What is that??? Is this how you treat your customers?? And you expect them to recommend you? And stop charging me for default fees that you are creating yourself. There's always money in my account on my debit date but you always charge me default fees this need to stop or I'm canceling this contract! Now send me all my statements and give me a detailed explanation of every cent added on the statement. My contract is R359 I don't understand why I'm paying R607 you explain this to me asap!
