BAD CUSTOMER SERVICE

Mr Price have the worst customer service ever, I have an account with Mr Price and requested for a credit limit increase i filled in the form and the store faxed it together with my bank statement after a week i went to the store to find out what is happening they told me to wait for my new statement if the credit limit request was successfull it will show on there, not happy with that response i called the call center only to be told that i do qualify for the increase but the confirmation needs to be done over the phone i wanted to give the lady on the other side my contact number but she said i need to go to the store to fill in a form to change my number. I went to the store and filled in the form and they faxed it with my ID copy. After a few days no response and i went to the store again and they called the call centre only to be told they never received my documents the lady that assisted me let me fill in another form and faxed it twice with my ID copy even gave me one copy to keep as proof that the fax was delivered. Today after waiting for the call again I called the call centre again only to be told by a lady named jacky that they haven't received anything and that i need to go to the store again and find out what is going on i told her i went to the store 3 times already and have a copy of the fax that showed delivered she answers with an attitude there's nothing she can do its my job to go to the store again and short it out. I mean how can it be so difficult to update details and what fax numbers are they using if everyone gives a different fax number if this is the stuggle i need to go through to update details i would rather close the account
