Cellc

Had so many issues with cellc. I bought a contract phone and the agreement was R320 but after few months they started debiting R520 which was not the agreement. Got a router last month on the 11th on the 16th they deducted R211 which was told its a connection fee on the 25th they deducted R108 and when I called they told me they wanted to see if I have gave the correct banking details and again been told tht R211 is not a connection fee, connection fee is less than R200. So I asked tht they must come collect theirrouter and It had 6GB tht only lasted for a day, so I don't see myself saving any cost. And now I see the statement of R600 for what not exactly. Is my bank a field where cellc plays on?
