SICK AND TIRED OF MTN

I have sent Mtn my proof of payment for a payment I made that was not allocated to my account, when I sent the list of successful transactions the customer service consultant told me I must send the proof of payment for the transaction to MTn in PDF format so they can look into it. I must do MTN account jobs for them???? <br> <br> Why does the amount differ monthly as this is a top up account and should always be the same and I top up if I need. My line gets suspended and the sms they send me are ridiculous They send me an sms when I complain about The R350 unallocated to my account saying yello - confirmation of payments arrangement for R350.00 (I have paid it already) then today I get an SMS saying friendly reminder payment of R350.00 due today. Mtn either ignore me or send me waffles which don't solve my problem. My advise is do not use MTN as your service provider. I am so sorry I have 5 contracts with them but will not renew them. <br>
