QUICK TO GIVE LOANS BUT NO AFTER SERVICE

Hi, even after your reply the issue is STILL not sorted. Since this morning we have had to make 3 calls and 4 emails. My mother has - Changed her cell number; removed the old number which is now my number; she even called now to have her mobi money de-registered, but we were told that a request will be sent to do this (and we know of experience that these "requests" do not get processed unless you phone again a few times and demand it. Another concern is.. how is it possible for me to log into my mom's account with MY ID and MY Password when the only resemblance on our account is the phone number? Seems to be a lack in your security. In other words you can mistype your phone number and it will just link you to any account that has that number????
