PATHETIC SERVICE

I am a customer of MTN for the past 20years.During March this year I upgraded my phone in Paarl.I dont know if the assistant at the branch made an error with my new contract,but to cut a long story short,I've received an account for over R4000.<br> Upon investigation,I found a mistake on my one number of nearly R2000.<br> I immediately lodged a complaint /investigation and the lady gave me a reference number.According to her I would be notified within 2weeks.....NO RESULT<br> After holding on for hours,explaining my problem to various assistants,getting new reference numbers even sending a fax to the credit controller working with my account to contact me.....STILL NO LUCK!!!!<br> This morning I was informed by sms that my service will be suspended in TWO DAYS time.Guess what????....I was cut off this afternoon.....and to top it all... I was paying my account every month in good faith(less the amount of the mistake )<br> I have proof of payments.My question to MTN......do I as a loyal customer for 20 years still want to be associated with you.<br> What more must I do to get this matter sorted out.....my phone is my income and are used as a business phone on a daily basis
