Terrible service ever

Went to Ccell store @cresta mall 2 get my upgrade on my phone but the lady who was assisting me didn't know what she was doing course she changed the plan that I was using without explaining what she was doing only 2 find out now that I can't recharge my account to buy data... Then when I called Ccell customer service to sort this out it took them 5 whole days to get back to me,then the woman who was helping me through the phone sounded like she was half sleep or not interested in helping took me to go back to cresta where I got my upgrade & that they can sort out the problem that I had and failing to tell me that I'll have to wait for 3months to sort this out.... I freaken not happy with the help I got there course the very same woman who did all this mess was helping me then helping another customer behind me... I disappointed in the service that I got and want this matter to be sort out ASAP with out me having to pay a cent more to Ccell I'm really tired and very angry of what has happened and wish I had just cancelled my contract with Ccell!!!!!!!
