MFC late replies and no feedback

I app**** for a payment holiday early March for months April - July, I emailed all the necessary documents that were requested and received no response from MFC. I then decided to follow up with them on the 14th of April only to be told that one of the forms i sent was wrong, but all this time no one said anything.Tried my best to reply quickly and send in the correct form because they needed to have all the documentation 2 weeks before my next installment. Anyway it was approved.....and this morning .....SMS..... Installment went off my account. It is really frustrating that i have to now surfer financially because someone did not do their job. I have been trying to contact the MFC call center for the past 2 weeks with no luck.
