PATHETIC SERVICE FROM STAFF MEMBER AND MANAGER

My contract was due for an upgrade, so I visited the Cresta store on the 25 September, Tumelo had assisted me with the paperwork. This was my first time ever dealing with an upgrade I kept confirming with Tumelo if there was any additional costs. He assured me a few times that there was nothing additional and the only difference is my monthly subscription. The store was very busy and everything was done quick to get to the next customer. To my surprise I got a statement of R1500. I went to the store and spoke to the manager Irfaan Sahib who promised to investigate and get back to me in the week. NOTHING HAPPENED! I went to the store this weekend and was disgusted that Tumelo **** to the manager who said he called me. Irfaan showed no customer service and mentioned there is nothing he can do. I cannot understand what is his role as a manager if he is so unreliable and ***********. He promised me a call today. PATHETIC!!!
