Pathetic services

I am having the worst experience with mondo telkom. I took out a contract in August for 2 cellphones where my premium is R430. In February I was debited R670 and I reversed the premium as that was not what I agreed on. March they debited the correct premium from my account now in April I received a message saying my account was in arrears and received a debit order around R1280 from my account. I have been trying to get a hold of them but they are forever busy and I have to hold on. I am wasting my airtime and I am still not getting a hold of anyone to assist me. This is the worst service I have received. Please contact me urgently to sort this out
