*****ing pensioners money

After numerous phone calls, visits to store, Cell c have still not resolved or responded to the issue of double debiting my pensioner Mom's account - its been 2 months!! Also despite changing bank details, they've cut off said account, as apparently they dont understand how to link 2 or more cell numbers to one account - still cant get an invoice that reflects correctly and so of course they didnt change bank details for the account..which considering its one person you hold responsible.. you'd think that was logic. Oh and best of all, they consider my mom "in arrears", refuse to adjust the debit order yet they want her to upgrade..yes upgrade!! Shocking behavior by people who have been loyal customers and behaved ethically and honestly to resolve the mess made by Cell C - not even our fault!
