Disappointing service

Placed the order in May for store pick up but the store cannot find it.

I have been going to the store and I am give a run around regarding the matter and I have using my airtime to call the call centre as the canal walk store never their phones.

The order was bought on account and the account has now been paid up and closed. The store now wants to refund me with a gift voucher which I refuse to accept as there isn’t anything I want from the store, so what am I going to do with the voucher!
