Pathetic Service once again

For the last 4 months MTN has been double billing me R 274 per month instead of my contract amount R139 and now I am sick and tired of this nonsense as for the last 2 months I have called them with no resolve. My first call dated 3 Aug between 2 - 2:30 pm and last Tue *** and yesterday around same time with ref - RAQ *** and spoke to Simalele and now I must still contact the credit department to follow up on there mishap on my account that I have now for over 11 years. Please sort my credit to my bank account immediately and make sure my installment are correct or I will migrate to Cell C and there is no going back and I have another no. as well on contract that I will move also<br> <br> Poovendren<br> PS please listen to all my calls to MTN as your staff from sales to customer service dont know what they doing<br>
