Lying about Customers

I am disappointed in the way Foschini do business. They have been calling me about a being a club member and I have missed several of their calls. On the 13th June I spoke to some lady who was telling me about the benefits of being a club member and I told her to give me a call on the 15th June and she did not call me on the agreed date instead I was surprised to receive an SMS on the 25th June 2015 welcoming me as a Foschini member. I am disappointed in the manner in which the whole thing was done Foschini. So with all due respect may you please cancel the club membership that I did not agree to in the first place. If you say that I have agreed may I please have the recordings. If I do not receive any response from you I will be taking the matter further.
