Poor Customer Service

I was contacted by summer mobile on or about 16 May 2018 by a person by the name of Zain to upgrade my MTN contract. All went well except that he failed to e- mail me a copy of my contract ,as promised. The handset came with 30G of free data which MTN refuses to load onto my phone untill I can provide them with a copy of my contract. I have been sent from pillar to post by MTN for more than 2 weeks as a result of summer mobile's failure to provide me with a copy of the contract. And since the contact number on their website is incorrect I' m hoping to resolve my contract issue through this forum, as I have no other means to get in contact with them. It was my first time to deal with summer and most definately the last!
