Unhappy client

MTN is starting to get on my last nerves. I have two cellphone contracts and they always split the amounts on the debit order which I didn’t have a problem with at first, now they debit on different days even though I have one debit order date. I called last week to tell them that I didn’t see the debit order for the second amount, and I was told by the call centre agent that it went through. Today I get an SMS to say the second amount didn’t go through and I need to call them to make a payment. If this messes up with my credit profile, MTN you will regret this coz I always make sure all my bills are paid on time. Someone needs to call me now to sort this mess up ASAP!
