Incompetence for a IT company

My issue with Vodacom ,specifically the VodaPay, has become utterly ridiculous at this point. I am flabbergasted that a Telecoms/Internet is unable to resolve a technical IT query. As stated in my previous complaint , I said that I am unable to make payment towards my Cash Advance on the MyVodacom App due to a technical glitch. Not one of the possible solutions you provided has worked and you keep closing the tickets(IT IS NOT RESOLVED). It is now become a matter of urgency whereby it needs to get resolved as it affects my credit rating, and this has been going on now for 6 MONTHS !!! You need write off the balance to compensate for my inconvenience (its not like a couple of hundred rands will hurt your profit) as it is influencing my credit applications and remove it from the credit bureaus .......
