Automatically Downgraded line

Shortly after taking out my 100/50 Bitco account, Openserv announced that they were upgrading all existing user lines and that the 100/50 service would become a 200/100 service withoutfurther cost. BITCO duely upgraded the line to 200/100 with no additional charge. On 30 March 2022, i received a message that my 100/50 Bitco account was migrating to web africa. Concerned about the speed downgrade, i used the whatsapp service to contact webafrica about this. After some time, the agent confirmed that the line ought to have been a 200/100 line and that i would be contacted in this regard. It appears that the line was downgraded as per their email and no communication from the agent who spoke to me since.
