P-Square signed an ambassadorial deal with the company some years ago, which was usually renewed after expirations.
But recently, members of the group have had it rough due to misunderstanding among Peter, Paul and Jude Okoye, who has been their manager since the birth of the group many years ago.
Also, it was learnt that at the recent grand finale of Dance With Peter, sponsored by Glo, Peter allegedly had a misunderstanding with a representative of the telecoms company.
It is not however certain if the reported contract termination was because of the crisis rocking P-Square or the alleged brawl with Glo rep.
Both parties are yet to make official statement on the matter.
