Inappropriate behavior

First of mobicred sends me a sms saying they cant get hold of me while no missed calles on my phone, im taking this as them just not wanting to fork out the money of making a call to their customers. Then after sitting for 5 minutes on all hold being number 2 in the que i hang up and tried their WhatsApp service, here after guessing a selection of 'accounts' since there was no option relating to my query, received no further response on WhatsApp., then send a email to customer service, still waiting on a response. then tried to phone again, this time i got through but with their line being so bad i could hardly hear what they were saying. So all of this only to get to a point where i am told because i made more then 2 purchases in 24 hours my account is locked, this i can accept but then to unlock my account i must take a selfie on the internet for facial recognition....so they are forcing me to use a method not initially agreed upon and assuming i have a working smart phone capable of this, which i don't. Will be pushing to pay the outstanding amount and then close this account!.
