Suspended line

Cell C suspended my line due to the fact that my debit order did not go through. The date arranged was the 22nd and the debit order went of on the 26. Cell C advised me it is an issue with my bank. so the account was not paid. This is a contract for my daughter and now she cant contact anyone in emergencies. I have also asked that no communication goes through to this phone from Cell C but they did that anyway. Very disappointed.
