Bad Service or Possible Delay Tactics so they do not Honor advertised Promotions

Teljoy had a special for Black Friday which I app**** for the special on Monday 23rd November 2020. The Special expired on 29th November 2020. Initially their response was quick. The very next day I received a request via email and text that I need to submit further documentation for my application. I did submit my documentation by Wednesday 25th November 2020. In fact I have sent the documentation 4 times now and they continuously send messages saying that I need to submit documentation. When I tried calling them on Thursday to follow-up the customer service basically shouted at me saying that I must just wait for the Application review team to contact me. Needless to say I am still waiting for someone to contact me and have now missed out on the Promotional Pricing. I think that this has been their tactic the whole time so that people do not gain from a promotion that has been advertised. They have absolutely no other contact numbers besides the customer service number and they refuse to assist at all. Very bad service and false advertising, I will not recommend them to anyone.
