CALL LIMIT FRUSTRATION!!!

Well, my french is pretty good and i certainly expressed that in my email to MTN, more specifically Goodness Khoza. In essence i initially expressed via email my concern that my call limit was not sufficient - R897.00 (even though i have had the contract for over 15 years and never once ever not paid my bill as it is on debit order and used for business) however someone at MTN and whose ****roach fell off the cork, thought it a wise decision that my call limit be limited to R897, because i was moved from Nashua, which with whom my bill was often in excess of R1000.00. Anyway, that being said, i was proactive and at the beginning of April I warned of the fact that the R897 was to breached easily in my contract and i would be extremely unimpressed if my phone was to be blocked - well needless to say it happened today and no-none at MTN was proactive nor gave a damn that this may have happened. So, now, i cannot get hold of the call center, i cannot use my phone and i still pay a service provider for a 'limited' service which in the past has never been the case!!! Clearly something is wrong with the wrong people in place. Sort it out you idiots!
