Olx India — olx india banned my user account

I have an olx account with phone no [protected]. I used to post ads on laptops and also buy from different users. Today while visiting the olx account in my mobile but it's deactivated and while going login, it says that your account is suspended. I immediately contacted the customer care about it and they said that my account is banned by the system due to unauthorized activity which is not true at all. They have also unfairly deactivated my previous account with mobile no [protected] also. I don't understand at all. I asked the customer care what is the main reason to deactivate but don't reply to me the reasons. This is completely unfair.
