cellc does it yet again!

I have 3 contracts with cellc. I was debited for close to 5000.00 this morning.when I called the contact centre and spoke to lerate he could not give me a direct answer as to why.he kept giving me the run around. The statements they send via email do not open up.how do I know what I am billed for if the person at your call centre can't even explain? This is unacceptable<br> ..<br> not only do I not have a valid explanation but also don't have enough for my other debits.....of which I will also have to pay fees for returned debit orders....wow cellc...u have proved yet again how efficient you are! After being with you for close to 10 years...this is not the service I expect to receive
